Thanks for posting this info. Assigning globally as this is another akien package that can't be assigned to him/her specifically. It needs an opinion as to whether this is specific to MGA or needs to go upstream. The fault seems to occur in widgets/qabstractbutton.cpp:664 which suggests QT, and there have been a few recent bugs related to the way we handle QT.
