gdb backtrace at gdk_pointer_grab breakpoint

Backtrace when breakpoint is set to gdk_pointer_grab() and gdb is running on a different display.

With gdb, the race can be easily reproduced: When starting grab, gdk_pointer_grab is called twice. If you ensure, that the second breakpoint is executed after mouse button release, the problem occurs.

How to reproduce:

1. Run gdb on a second machine and set breakpoint to gdk_pointer_grab
2. Shortly drag any image or link and release.
3. In gdb do:
bt
cont
bt
cont

Actual result: browser runs, drag is finished, but the browser still has a mouse grab.
