update-manager crashes when cancelling sudo authentication

[Chad A Davis]

Binary package hint: update-manager

Update manager was ready to install a small number (13 updates, 1MB download) of new updates today. After being prompted to authenticate via sudo, I selected "Cancel" (in order to update later instead), which caused Update manager to crash, after a long pause.

Update manager stays open, however. If I then select "Install updates" again and then "Cancel" the authentication, I can reproduce the crash.

I then went back and authenticated and successfully installed the 13 updates. Since my package information database was 14 hours old, I did another "Check", found more updates (78 updates, 66MB download) and again tried to "Cancel" the authentication, which again resulted in a short delay, followed by the same crash. I.e. it does not seem to be the unique set of packages, but rather than that the authentication failing always causes update-manager to crash.

Cancelling authentication in general, e.g. to change the date via gnome-control-center doesn't cause any crash. I.e. it doesn't seem like the issue is in gksu (I guess that's what's running behind update-manager) but rather in how update-manager responds to authentication being cancelled.

The crash does not happen when I enter an incorrect password, only when I press "Cancel".
