Update: With Ubuntu Software Center 5.3.14.1 in Quantal (at least with me on amd64), it appears there is no longer a startup crash. This update popped in shortly after I updated my system literally about 5 minutes after commenting on this bug. Guys, please update your systems now and see if the bug is still there. It should be gone. If so, we can mark this bug as fixed.
