you're kidding, right?

the first bug you linked to is an invalid mess. and you managed to link to the same report twice. hint: don't link to more than one external report, and if the report is invalid, it's probably not something you want qa to read, so don't bother linking at all.

#3  <signal handler called>
^ this is when you crashed. the stuff past this point is just cleanup so that you can run firefox again.

fwiw, your attachment is almost useful, except it's missing the critical bits:
No symbol table info available.
#4  0xb6dde63b in ?? () from /usr/lib/libcairo.so.2
No symbol table info available.
#5  0xb7c1d50a in ?? () from /usr/lib/libnspr4.so.0d

please install the -dbg packages for these libraries. then get a new stack trace.

fwiw, we don't generally have a use for an strace. we need a complete and valid stack trace. these come from things like debuggers such as gdb. however, in order for them to be able to give you a good stack trace, they need debugging symbols. information on installing those symbols (from -dbg packages on your platform) can be obtained from your distro vendor. 

as it happens, your vendor even has a wiki page specifically for this product, and it's in one of the bugs you linked to. in general it's a good idea to read things you want others to read....

https://wiki.ubuntu.com/MozillaTeam/Bugs

note that had you read that wiki you'd at least have symbols for nspr. sadly for unknown reasons they don't tell you to install symbols for cairo. please feel free to kindly suggest to them that they add it to the list. (you should really have symbols for: x, glib, gdk, and cairo in addition to the ones they list.)

First. I am not wasting time and efforts for kiding.

I am trying link diverse reports of bugs ( efforts of many many people trying help , inside of your limit of knowledge but are attempting. he may give a hand & no a punch ).
this is a recommendation wherefore bugs alike ( or but also repeated ) they may have faster solution. more bugs reports more people to help (I suppose)


second : in relation to the fact of the first bug is invalid (I showed others), look the review 19, the bug is invalid exactly because do not have a backtrace useful!!!! ( https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/184957/comments/19 ) 
 Look others commentaries and others bugs report , the number is frightful :(

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0?field.searchtext=&orderby=-datecreated&search=Search&field.status%3Alist=NEW&field.status%3Alist=INCOMPLETE_WITH_RESPONSE&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&field.status%3Alist=FIXCOMMITTED&field.assignee=&field.bug_reporter=&field.omit_dupes=on&field.has_patch=&field.has_no_package=



My bug reports ( and not yet is invalid :)

https://bugs.launchpad.net/ubuntu/+source/firefox-3.0/+bug/217032

and I used the instrunctions from https://wiki.ubuntu.com/MozillaTeam/Bugs
 

I will try install all  dbg and dbgsym packages ( https://wiki.ubuntu.com/DebuggingProgramCrash )
using this script
#!/bin/bash
echo on
dpkg -l | cut -c5-40 > /tmp/loop.txt

for arquivo in $(cat /tmp/loop.txt); do
        echo trying DBG "$arquivo-dbg"
        apt-get install -y --force-yes "$arquivo-dbg"
        echo trying DBGSYM "$arquivo-dbgsym"
        apt-get install -y --force-yes "$arquivo-dbgsym"

done

the libcairo2-dbg package is reallly missing from recommendation at mozillateam.

root@unstable-desktop:/home/unstable# dpkg -S libnspr4.so.0d
libnspr4-0d-dbgsym: /usr/lib/debug/usr/lib/libnspr4.so.0d
libnspr4-0d: /usr/lib/libnspr4.so.0d
root@unstable-desktop:/home/unstable# dpkg -S libcairo.so.2
libcairo2-dbg: /usr/lib/debug/usr/lib/libcairo.so.2.17.3
libcairo2: /usr/lib/libcairo.so.2.17.3
libcairo2: /usr/lib/libcairo.so.2

thank you for his considerations, links and by attention.

I tested with the version at http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9pre) Gecko/2008041504 Minefield/3.0pre

And crashed too

I observed that at java.sun.com main page print to file ( pdf option)  always crash
Important: ps option don't crash ( yet :)



the firefox had detect by itself and send the following crash report:

Comments: I was make a test with the lastest nightly trunk to test the bug report https://bugzilla.mozilla.org/show_bug.cgi?id=429071 and continues to crash when I print to file ( pdf option) on site like java.sun.com

Unless we have symbols for your cairo, the report won't actually be any more useful than what you've already pasted.

sadly, the output you pasted from crash reporter is absolutely useless. please load about:crashes and copy the bp- id.

we want to get the crash reporter ui improved, but we ran afoul of a localization freeze, so there's probably not much we can do about it for 3.0 :(.

Comment 7

[bergos]

Attachment: second output with more debug symbol installed ( fixing missing important files)

Comment 8

Attachment: list of all packages installed at my system( I installed all possible dbg and dbgsym packages)

Sorry for inconveniences, I am learning and each bug report I learn more.
thanks .

oh, heh, i was wrong about cairo. sorry. in our builds, we build our own cairo. in distro builds, you get system cairo.

thanks, both stacks are useful. although sadly they aren't identical.

[Martijn Wargers (dead)]

I just filed bug 429678, which might be related to this bug?

Comment 12

[Mats Palmgren (inactive)]

I'm pretty sure it's the same problem as bug 429678.  Applying the patch
there fixes it for me (on Linux).
