software-center crashed with TypeError in _parse_menu_tag(): 'NoneType' object is not iterable

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

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.

To reproduce this issue, simply open "Ubuntu Software Center" in Xubuntu Oneiric after installing.

Thanks for taking the time to make Ubuntu better!

This bug was fixed in the package software-center - 4.1.23.4
