I've tracked this down further.

The Gnome developers broke gtk's clipboard support on multi-screen
setups.  You can only paste selected text from a gtk-3 app when the
destination is on the same screen.  Because of the way I work, I'm
usually cutting and pasting between screens.

That has always worked find in gtk-2 (and all other toolkits I'm aware
of).  I'm pretty sure this is has been a known probelm for a long
time, but the developers all use single-screen systems, and therefore
it's either not a priority or they can't figure out how to test it.
