Firefox crashing (SLED 10).

[amack]

Recently my Firefox has begun to crash A LOT. Doing trivial things such as Clicking on the Menu 'file' button. I am not aware of any upgrades that would have caused this. It behaves this way even in safe mode.

The following is the strace output from right before the crash happens. Does anyone know how to debug this, it looks like maybe a glibc (libc.mo) problem but that hasn't changed recently.

Any advice would be helpful. I've tried everything else suggested for most Linux/Firefox problems with no success, I think my problem may be specific to my setup. I noticed this problem started happening after installing some video plugins (mplayer), although it still happens even if I run in safe mode or remove the plugins.

Ok, I was fed up with firefox crashing so installed opera
$ sudo smart install opera

Once this installed, firefox was fixed. I am guessing that there was a shared lib or something that opera updated. Strange.
