update-notifier crashed with SIGSEGV in g_hash_table_lookup()

[Wise Melon]

I am sorry not to be able to be very helpful, but I just found this .crash report from a while ago in /var/crash so I'm not entirely sure what would have been happening at the time of the crash. Though likely something along the lines of either it closing by itself or me trying to close it and it crashing.
