The cause of this problem is explained as DELLs not sending the Key Up events. In my case I see a tight loop of KeyPress/KeyRelease events (in xev), as I have explained in bug#288579 (https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/288579), which was closed as a duplicate of this. Is it really the same bug / root-cause?
