cause was determined to be the use of a theme with firefox, specifically the silver skin theme. firefox functions when using default theme
Same here, further investigating gives that ANY gtk-app, when using baghira as qt theme and qt theme for gtk, will segfault just changing desktop. (tested with gkrellm, I don't know if this apply to any or just any-SKINNED app.)
well, it was figured out it is the theme. I will mark this as fixed. And FYI, I added a gtk-engines-qt cvs snapshot that should have some fixes :)
