Thank you hammady for submitting this report.

Could you please try to obtain a backtrace by following the instructions on
[1], or upload the crash report that probably was generated during the crash
and that should be located at /var/crash/ to [2].

Please indicate which extensions/plugins do you have enabled; and if this crash
is reproducible describe the steps that lead to it (it is very important for us
to have a test case for each crash).

This will greatly aid us in tracking down your problem.

Thanks in advance.

Hey,
I found what the problem is
the download target was a fat32 partition, it has an inherent file size
limit of 4GB. So firefox crashed because it did not expect this to happen i
guess!
I discovered this because I splitted the large file, copied it to the FF
machine (using wget) then tried to merge the files but I got the error:
file size limit exceeded with the file being 4GB also!
Please tell me if you still need any reports, btw I uploaded the crash
report already.

Thanks,
Hosam Hammady

Good feedback, thank you.

We need the symbolized stacktrace of the crash in order to complete the
report.

The crash report you have submitted (which is the *small* crash report)
as you don't have installed the dbg package for firefox is useless (you
can see in it a bunch of useless "(no debugging symbols found)").

In order to retrace the coredump of the crash with debug symbols we need
you to upload that coredump file which is attached in the *full* crash
report located at /var/crash.

So hammady, please, as stated in my previous post: "Could you please try
to obtain a backtrace by following the instructions on [1], or upload
the crash report that probably was generated during the crash and that
should be located at /var/crash/ to [2]."

Thanks in advance,

I tried to upload the detailed report twice and it says:

Sorry, you can't do this right now

Launchpad is offline at the moment for maintenance. It should be back,
better than ever, soon. Thanks for your patience.
The Launchpad team

Please download it from http://www.hammady.net/ffcrash.tar.gz
