The bug is caused by atk-bridge, if it's present in GTK_MODULES, the bug happens.
Not sure where to re-assign the bug though but it seems to me like that's an atk bug and not an ubiquity bug (as ubi-partman didn't have any change related to accessibility in months). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/939450 Title: ubiquity crashed with TypeError: argument of type 'NoneType' is not iterable in ubi-partman.py To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/939450/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
