--- Comment #6 from Johan Palmqvist johan.palmqvist@home.se 2010-06-10 02:22:03 --- That's weird. I just tested both the demo and the retail version on 1.2-rc2 without gecko installed but both crashes the same way.
Note that I currently don't have access to the machine in the original post. This is on current Debian sid on an Athlon X2 with NVIDIA 9600GT (proprietary driver 195.36.24).
