firefox crashes [@nsXMLHttpRequest::StreamReaderFunc]

[annelid]

... when adding information to family trees on ancestry.co.uk

Binary package hint: firefox

I am adding information to personal family trees on www.ancestry.co.uk

It doesn't crash straight away, I can fill in maybe 3 boxes of information for an individual and then it crashes

the problem report for firefox said to attach this...

var/crash/_usr_lib_firefox_firefox-bin.1001.crash

Hello annelid,

Thank you for the bug report, you can add the crash report by clicking on the "Add a comment/attachment" button below the comments.

May I also ask if this is reproducible every time? Or has it only happened the once? Also has the problem occurred on any other websites?

Thank you, Alex.

I can't get the crash report to upload or to send it in an email.

the crash is reproducible every time I use ancestry, and I've not had
any problems on other sites.

Hello annelid,

Could I ask you to try a new profile? (Instructions can be found on how to do this on the link below), this will set your installation to use a blank profile, free of extensions etc. This will help us eliminate that.

If that fails to rectify the problem could I ask you to try to obtain a backtrace report? Instructions on how to do this are located here:
    https://wiki.ubuntu.com/DebuggingFirefox
This will enable us to find the root cause of the problem so it can be fixed ASAP.

Thanks again, Alex.

I renamed .mozilla to .mozilla.old and tried again. All my bookmarks etc
were lost as expected.

The problem still occurred.
Trying to add missing debug symbols gives:

anne@rattle:~$ apport-retrace -d
/var/crash/_usr_lib_firefox_firefox-bin.1001.crash
Traceback (most recent call last):
  File "/usr/bin/apport-retrace", line 189, in ?
    debug_dir = prepare_debugdir(report, options.cache_dir)
  File "/usr/bin/apport-retrace", line 147, in prepare_debugdir
    needed_deps.add((pkg, dependency_versions[pkg]))
KeyError
anne@rattle:~$ echo $?
1

I'm running ubuntu edgy-eft all up to date.

I got a backtrace attached though. Maybe it's time-sensitive? It was
harder to trigger running under gdb. Hope it helps.

Anne

I can't see what lauchpad has done with the attachment, so I'm adding it
inline this time.

Seems like a usable trace. Setting this to confirmed and am going to send it upstream in a minute.

Thanks, Alex.

We are sorry that we do not always have the capacity to review all reported bugs in a timely manner. You reported this bug some time ago and there have been many changes in Ubuntu and Firefox since that time.

Do you still see a problem related to the one that you reported using currently supported versions of Firefox and Ubuntu? Please let us know if you do otherwise this report can be left to expire in approximately 60 days time.

Thank you for helping make Ubuntu better.
