random X server crashes (with backtrace), any clues?

[john terragon]

Hi.

After a dist-upgrade on my debian installation I'm experiencing "random" 
crashes of the X server, always with the backtrace that you can find at the end of this
email. 
The dist-upgrade was rather large and a lot of components were updated, like the X server, 
mesa and kde. I don't think it's kernel related, as the crashes happen with various kernel versions 
that I was using before the upgrade.

Can anyone offer any clue?

Thanks 
john
