Shortcuts interpreting Alt Gr as Ctrl Alt or stretch is broken?

I updated to 4.4 recently at it seems that the program no longer lets me use the default shortcuts for layout stretching - { and } - which on a Swedish keyboard are on Alt Gr 7 and Alt Gr 0 respectively. I can still type the characters out when adding text in the score, but if I try to press the key combo to perform layout stretch nothing happens and when I try to rebind the keys for { and } it says that the input I perform is "Ctrl Alt {". Even after accepting that combination as the new shortcut, nothing happens when I perform it.

Update: It would appear that whatever I add as a new shortcut doesn't work. The menu buttons are still working, but having to enter the menu for each and every de-/increase in bar width simply doesn't cut it workflow-wise.
