Public bug reported:

The multimedia keys (almost all non-standard keys) on my keyboard do not send KeyRelease events when they are released.
If key-repeat in keyboard settings is activated this causes the system to infinitly repeat the action assigned to the key.
In case of Vol+/- keys this leads to a flickering of notify-osd with volume at max/min. 
worse: Pressing the search button keeps opening search window until system hangs.

I believe this is a solution for the bug:

switching to a tty1 and back to X releases the buttons.

output of xev when pressing the Calculator button several times followed by the Eject button:
