Firefox and thunderbird crash when opening a gtk window

[Yachar]

Bug reproduced with Firefox, Firefox-Granparadiso, Thunderbird.

Newly updated Gutsy from Feisty (apt.sources modification and apt-get update && apt-get dist-upgrade without any problem).

Steps to reproduce :
- Thunderbird :
    * launch thunderbird ;
    * use the menu to open a "gtk window" (e.g. Edit -> preferences. Works when creating a new mail or answering a mail too, but not when opening Account settings) ;
    * thunderbird either crashes immediately or gets stuck forever (need to kill -9 it).
- Firefox & Granparadiso :
    * launch Firefox ;
    * get somewhere to download something (e.g. kernel.org) ;
    * firefox gets stuck (need to kill -9 it) when clicking on the download link. Using the menu to open Preferences crashes firefox too.

Some more tests tell that changing gtk/gnome or firefox/thunderbird themes has no impact on this bug.
I'm using an i386 version of Ubuntu on a dual core AMD64.

I couldn't find an existing bug that looks like this one, but there are so many that I may have missed it... sorry if this is the case...

I'm available for further testing / detailed information.

Sounds a bit like the firefox theme/border-free crash bug we are
getting. Do the crashes look similar?

You're probably talking about this bug : https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/129007
And you're apparently right ! Switching theme to Clearlooks solved the issue.

I thought it was not related to themes because I tried 4 of them, but all triggered the bug... sorry for the duplicate, and thanks for solving my problem so quickly :)
