I couldn't reproduce this bug and I didn't find any duplicates.
I am not exactly sure what happened right before the crash. I was applying today's update, and it said there was an error about broken packages. I was quitting so I could use the command-line apt-get to figure out what was going on, and then I got this crash. Oddly, apt-get does not report any problems.
One further point: one reason you may see no duplicates is that I am running the beta of the latest version.

Git commit 0a6b3a90c1c877af9469dcd7b8f36dc74bf99013 by Jonathan Thomas. Committed on 12/02/2012 at 04:33. Pushed by jmthomas into branch 'master'. Exit synchronously in the case of a backend initialization error. The way that the asynchronous error reporting currently works will not close the application "quick" enough when QApplication::exit is called. In the future, the smart thing to do would to make QApt::Backend::reloadCache return a bool, but that would break ABI and will have to wait for QApt2.
