Using gnome-shell git revision ea3b2a57, if I use the Activities view (move mouse to upper left) and try to take a screenshot, the screenshot window appears in the activity view, and then the shell crashes immediately.  The entire output is:


do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly.
Try adjusting the vblank_mode configuration parameter.
Panel leaving: a new panel shell is starting.
