I think this is the same problem as the one fixed in bug #21337,
except that the cause for the problem is different: where it was
GnuTLS in that bug, it's something else in yours.

So I suggest to read the description of the root cause posted by
Robert Pluim in http://debbugs.gnu.org/cgi/bugreport.cgi?bug=21337#31,
and then look for something very similar, but involving other sources
of input events, perhaps D-Bus.  The symptoms you describe exactly
match what he explained there.
