Possibly not even related... I was seeing a similar problem in .26 or so and 
it turned out to be caused, IIRC, by SCIM (in Gnome) and the KDE "Input 
Methods" system. However my problem might not be related, because this even 
stopped Alt-SysRq-K from working - and it only happened if I was holding down 
a "modifier key" for a longer than average (say 30 seconds). I never reported 
this because I soon after got tired of that distro (I was giving it a try at 
the urging of friends) and replaced it.

The problem has not re-occurred since.
