It's an X selection request event.  I'm not sure where the request is
coming from---Gnome's clipboard manager, maybe.  Setting
interprogram-cut-function to nil also inhibits the problem.

OTOH, I don't see why the pending input doesn't trigger for Emacs 23,
since M-w copies to the primary selection there too.  Maybe it's a
subtle effect of one of the changes to the primary selection code a few
months ago.
