update-manager crashed with TypeError in _get_last_apt_get_update_text(): unsupported operand type(s) for /: 'NoneType' and 'int'

[Jean-Baptiste Lallement]

Binary package hint: update-manager

ISO Testing Xubuntu Alternate AMD64 20110201.1
ISO Testing Ubuntu Alternate i386 20110201.1

I installed Xubuntu from the Alternate ISO.
After login, I clicked on the update-notifier icon on the notification area.
There was 11 updates, and installed them all.
This crash report triggered after the update.

This is reproducible when I do a new installation.

Thanks for reporting this bug and any supporting documentation. Since this bug has enough information provided for a developer to begin work, I'm going to mark it as confirmed and let them handle it from here. Thanks for taking the time to make Ubuntu better!

If the system is completely shutdown and restarted before running the update manager, this issue does not occur.
