@Joey: Thanks so much for digging into this. I'm confirming that it worked for me as well. I updated the ticket description.
** Description changed: - Not sure what I did to cause this. + 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 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.
