Comment 4

[Andreas Franke (gone)]

Confirming bug on PC/Linux. I saved the attachment to a local file
"offline.html", rebooted standalone, ran mozilla, and entered the file name in
the location bar. After pressing return mozilla segfaults:

#0  0x40091e59 in nsXPIDLString::nsXPIDLString ()   from libxpcom.so
#1  0x40092cb8 in nsXPIDLString::nsXPIDLString ()   from libxpcom.so
#2  0x40092f30 in nsTextFormatter::vsmprintf ()     from libxpcom.so
#3  0x40092ec8 in nsTextFormatter::smprintf ()      from libxpcom.so
#4  0x40951d8d in nsWebShell::OnEndDocumentLoad ()  from libraptorwebwidget.so

Changing OS to All. Needs to be reassigned.

Trying Networking component because this is an "offline" bug. CC self.

Comment 6

This doesn't seem to happen on 2000060808 (win95).

Comment 7

[kirun]

To avoid confusion, when I said "offline" , I meant not connected to the
Internet, not in offline mode.

Although this now doesn't crash the browser, it still causes problems. The best
behaviour would be to give an option to go into offline mode, or retry
connecting to the Internet.


As OS is "All" I don't want to mark as "fixed" because I only have access to a
win95 machine.

I have found why the browser has not crashed with this recently (at least on my
system). It seems all the images had cached copies. The crash seems to occur
when there is no cached copy.

I think I have seen a dup of this in the webshell/uriloader land. over to 
rpotts.

gordon, any thoughts?

Comment 11

[Frank Tang]

I cannot reproduce this with 10/16 window branch build. I try the following
1. I download the attachment.
2. I change to attachment to point to another image which does not exist.
3. I unplug the ethernet from my computer
4. I load my local page.
It won't crash now.

[e-mail]- can you still reproduce the crash? If not, can we take out
the crash from the keyword ?

[Frank Tang]

I try the same procedure above on recent Linux build. The moment I unplug my
Ethernet cable, Mozilla freeze. So... I cannot reprudce the problem . After I
plugin it back, it run.... I think that is a seperate issue.

[kirun]

I am currently unable to reproduce the crash. (2000101804 on win95). I'll post a
trace if I can get it to happen again.

This crash may be related: (talkback TB19569208H)

I had two open windows, both marked as being offline, and I was not connected to 
the Internet. I opened a copy of the CSS1 spec, which has references to some 
files on the w3c site. No dialup attempt, just a crash.

This bug is a "futured" or "untargeted" bug which has been "resolved/works for
me". Most bugs meeting this criteria are usually somewhat out of date or working
in the current builds.

If this bug is not happening for you in a recent build (such as the Mozilla
daily build, Mozilla 0.9.3, or Netscape 6.1), please use the friendly "Mark bugs
as VERIFIED" radio button to set this bug to "VERIFIED/WORKS FOR ME"
If you reported the bug on a platform (e.g. Linux) and other contributors
reported on another platform (e.g. Mac OS), please comment that it works for you
 but do not verify it yet.

For these multi-platform bug reports, we need to verify all reported platforms
-OR- create new "still broken on platform X" bugs when you verify.
