Description of problem: I searched for cheese on YumEx, found it and installed. Once done, and launched, the crash happened along with this "misc.py:1018:write:IOError: [Errno 5] Input/output error."! It can be reproduced by installing.

It looks like (for some reason) the post-install script for the -libs subpackage was not run, and as you mentioned YumEx, I guess that is related. Can you run "glib-compile-schemas /usr/share/glib-2.0/schemas" and see if that fixes the problem?
On closer examination of the log, it seems that the postint scripts (to run glib-compile-schemas, among other things) have not been run before launching Cheese, so this is not a Cheese bug, but probably a YumEx one.
