firefox with firebug crashes x (ati radeon)

[Piotr Kęplicz]

From time to time, visiting certain pages with Firefox causes X to crash with:

Backtrace:

For example, I get such a crash with the current version of http://planetkde.org (also with a copy saved with Chromium). I tried disabling all the addons and it seems that the crash is caused by Firebug.

Using Ubuntu: 11.04
Firefox 5.0+build1+nobinonly-0ubuntu0.11.04.2
Firebug: 1.8.0 through the official Mozilla addon channel
xserver-xorg-video-radeon: 1:6.14.0-0ubuntu4.1

I experienced similar crashes also in previous releases of Ubuntu.

Piotr Kęplicz, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-ati REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.
