Comment 1 for bug 149559

This could be an X configuration or driver problem. Install libxine1-dbg (optional, but very useful for backtraces), then
  $ gdb --args gxine --sync
  (gdb) break gdk_x_error
  (gdb) run
...
  (gdb) bt

Also, you may find that at least one of the following works:
  gxine -V opengl
  gxine -V xshm
If so, you can edit the video.driver option in ~/.gxine/config accordingly (you'll need to uncomment it), but this isn't really fixing the problem...

(Bug 130696 may be relevant.)
