UnboundLocalError: local variable 'chosenModule' referenced before assignment

Happens when I open a media file not generated on my computer which supports playing mp4 files while my phonon backend doesn't. Simply showing a nicer error message should be enough.

Closing accordingly (I mostly use 'Fix released' instead of 'Fix committed' since the bug overview gets a bit messy otherwise. You can still look up the bugs if needed via the milestone it's linked to.)
