The first step would be to try to get a backtrace while running the
programs with the --sync command line option, since it's possible
that it's not the XQueryPointer that is causing the hang but some
earlier request.
Unfortunately, I'm not sure if either evolution or Galeon will really pass
that option through to the main part of the application ... they are both
somewhat complicated. But it's worth trying. And it should definitely work
for simpler apps. (You can tell if you are running the apps synchronized,
because it will be darn slow.)
