It started crashing again today. I grabbed some new state tarballs:
http://fushizen.net/aptitude-state-3.tbz2
http://fushizen.net/core.17966.bz2
I think I've figured out how to reproduce this:
* Open aptitude. Do any package install/upgrade/remove operation.
* When the operation completes, and aptitude says "press return to
continue", open another aptitude in another shell. It will SIGSEGV,
rather than complaining about the status area being locked.
