57982 - [crash] dragging thumb in scrollbar causes X crash

Status: RESOLVED WORKSFORME

(Core :: XUL, defect, P2)

Description

[sarnold]

Greetings.

I am using Debian's Mozilla m18, with Branden's XFree86 4.0.1 .debs on a
dual-celeron Linux 2.4.0-test7 computer, with a G400Max dual-head display
running Matrox's mga_drv.o to enable the two monitors.

Normally the whole system is rock-solid. However, there is one problem. Dragging
the scroll thumb with my mouse in mozilla will occasionally cause X to die a
horrible death. It is extremely quiet about errors. I *think* the only error
message is along the lines of "xinit: connection to server unexpectedly lost".

Using the scroll wheel or using the keyboard to scroll has yet to crash X.
Dragging scroll bars in other applications has not caused problems -- including
aterm and pan (which uses gtk and gdk version 1.2). Thus, I am reporting the bug
here.

Do you have suggestions on how I can get better output from mozilla when this is
happened for further tracing? Since all of X dies pretty quickly, my options are
rather limited... :)

BTW -- this has happened on many pages, but the most recent can be located here:

Thanks! :)

[e-mail], thanks for the report and your testing of Mozilla.  I
have not experienced any crashes like this in recent history but there are a
couple fo things that you can do which may help us track down th eproblem.
The first is to get a current build http://ftp.mozilla.org/pub/mozilla/nightly/
(look in the MTrunk directories, not the MN6 directories)
  You'd be surprised at how much has changed since M18.
The second thing that might help is to use a Talkback enabled build.  Talkback
builds generate a report on most crashes and send that report to a server I can
access. The report will contain a stack trace that should help us isolate the
problem.  There are two builds available with Talkback. The first is in the form
of mozilla-i686-pc-linux-gnu-installer.tar.gz and the second is
mozilla-i686-pc-linux-gnu-sea.tar.gz .
The installer-tar.gz is a small download (about 60K).  If you use this one then
you tar -zxvf it, step into the mozilla-installer directory it creates,
./mozilla-installer and it will launch an installer that allows you to specify
the packages that it will grab and install from the webserver.  Select Complete
or Custom (if you use custom, make sure the TalkBack package is selected).  If
you use the second option, you get the installer and all of the packages in one
download so the process is the same but it doesn't fetch the packages during
install.
Hopefully the talkback build will catch the crash and give you the option to
send in a report.  If you post the email address you included in the report or
the incidentID of the report I can retrieve a stack trace and attach it to this bug.

After spending much time trying to cause the Oct 25 8:30am build to crash by
dragging the main scrollthumb, mozilla finally crashed (signal 11 in the X
server) -- by using the scroll thumb in the "browse" window of the "Create new
attachment".

It crashed pretty hard, and no talkback dialogs came up. Is that the only way a
report would be sent back to you guys?

Reporting the same thing with 2000112909 linux

Steps to reproduce:

1. Go to www.mozillazine.org
2. Click on the Read More link in the build bar
3. Click on the link for bug 61334
4. Drag the thumb down to scroll

It crashes. I get no talkback screens.

Setting severity to critical as it is a crash
Adding me to CC

I crash on win32 build 2000112908 when scrolling the following URL:
http://www.greyhound.com/scripts/ticketcenter/step2.asp
and bug 61334.  Changing OS to all

[sairuh (rarely reading bugmail)]

interesting. the trace is practically identical to what i got in bug 60905
[different steps, and didn't kill X for me while on linux].

also noticed bug 59782, with similar trace [the beginning at least].

nominating for mozilla 0.8  This is ugly.

Trudelle: Can you offer a different milestone?

Nominating mostfreq, we're getting dupes.

Note: the stacktrace on this bug occurs in code that was added after this bug
was originally reported. However, the crash may be addressed by a patch on 
bug 61519.

retargeting to moz0.8, whenever that is, and priority P2

Comment 16

[[e-mail]]

X servers are trusted code and should not crash. If anyone reproduces the X
crash (ie your GUI and all apps vanish, the machine locks up or you are left at
the login prompt) please report it to XFree or whoever wrote your server. If you
are using proprietary drivers (as the reporter was) report it to the vendor.
No user application (like Mozilla) should be able to cause this.

Still, there does seem to be a Mozilla bug here worth fixing on all platforms.

[André Dahlqvist]

I don't see this any more with 2000113021 on Linux. Could it have been fixed by
the checking to bug 61519?

Comment 20

[Eric Vaughan]

If this got fixed and someone confirm and close it out?

Comment 21

[Azrael AOD]

suggest this be checked with the following URLs of dupe bugs:
http://www.nintendonation.com/main.shtml bug  61533
http://www.xdrive.com/ 61535

Comment 22

[John Morrison]

This was fixed by bug 61519, I do believe. (But reopen if this is still 
happening).

Comment 23

[Azrael AOD]

When you say it works for me... does that go for the following two bugs aswell?
bug  61533
bug 61535
