Thanks, I could reproduce it now.  I need to press Back and Menu keys
very quickly after each other.  If I press them slowly this doesn't
happen. And it doesn't seem to happen if I cancel the menu with another
keypress, I don't know why.

My assumption on what happens:
- Back key pressed -> ESC press delivered to application
- Back key released & menu pressed -> Menu opens before application
   window processes the ESC release
- Only after the menu goes away with a tap, the ESC release is processed
   by the application window.  As the interval between processing the
   press and release events was long, it's interpreted as a long press

I'm not sure how this could be fixed.  The X events contain a timestamp,
maybe this could be used for checking the event interval instead of
the interval of processing the events.

Currently the bug seems to have 0 votes.  Are the other users pressing
the keys in a way that triggers this bug too?  (I don't think I've ever
triggered this mysefl when using the device)
