There is a bug in TWM (and descendants) which can cause this.  Lucid 
Emacs 19.4 comes with a file etc/twm-patch which should mostly fix this.

I believe GWM had a similar bug, which I think has been fixed (but I'm
not sure.)

The bug does not appear to be *completely* gone, but I haven't yet been
able to come up with a reproducible test case; the TWM patch makes it 
much more rare.

There is also a bug in MWM (and I think OLWM as well) where they send
CurrentTime as the timestamp of a TAKE_FOCUS message, which the ICCCM
explicitly forbids.  There is code in lemacs to work around this.
