-- Information about the crash:
I started firefox from my favorites link, and that took my kwin down. Other open applications were xawtv, and sox to redirect sound.

My firefox has known issues for hang ups, because of the wrong ELF library. (This is a known problem because of 64 bit OS using 32-bit drivers in gtk?). Should not have any impact, but just state it to be specific.

 -- Backtrace:
