Bug description:
These types of crashes usually happen shortly after logging in, but in
this case, it happened much later. Crashing early doesn't seem to
happen with debugging info turned on, as it was for this issue.
For more details on this type of crash, please see bug #750386.
WORKAROUND: For some of us, this is caused by a corrupt
.config/dconf/user file in our home directories. Try removing this
file, and report back. Be warned, however, that by removing this
file, you will lose many of your desktop environment configuration
settings. If this is a concern, rename it and keep it around in case
contents of the file are salvageable.
