Status changed to 'Confirmed' because the bug affects multiple users.

This may also affect update-manager, which also dumps core on my 15.04, but I don't know any way to make update-manager emit underlying error messages.

Effectively, I am unable to do a release-uprade to 15.10 now, as both software-center and update-manager are inoperative.
