mem corruption?

is no good sign at all. since FF doesn't link Qt it's really deep down (glibc/kernel)

- did you recently update your system (HW/SW)?
- checked the system temperature?

I feel kind of dumb not thinking of that myself... ran a test and sure enough, it's my memory. 

I guess I should change the status of this to "resolved" in some way, it "Invalid" the correct choice?
Comment 3 Thomas Lübking 2010-11-02 00:56:00 UTC 
yupp ;-)
... errr, sorry about your memory :-(
Comment 4 Josef 2010-11-02 08:49:26 UTC 
Thanks! I got to keep half of it... so I can still use my computer, and the up-side is that's it's reliable now, and that's nice...
