This has just happened to me on 12.04 which is fully up to date except for todays updates (04/03/2012).
I closed the software Centre by clicking the close button and got no response. so, I clicked again and the Software Centre closed but then the Closed unexpectedly message appeared and apport did its stuff. This was the first time I have used software Centre since 12.04 went into beta 1 and this problem did not occur earlier. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/885726 Title: software-center crashed with TypeError in _get_combo_children(): object of type 'NoneType' has no len() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/885726/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
