Description of problem:

Evolution crashed on me while yum was updating it from rawhide. I got this in my
~/.xsession-errors:

evolution: xcb_lock.c:77: _XGetXCBBuffer: Forutsetningen (assertion) «((int)
((xcb_req) - (dpy->request)) >= 0)» feilet.

I've seen a lot of hangs in evolution earlier while running yum update from
rawhide and those have not necessarily been while updating evolution itself. The
backtraces from those also originated in libxcb so I thought I'd mention them here:
