Before I file a bug report I would like to see if someone else has encountered
the following before:

When I call gdk_pointer_grab with GDK_ALL_EVENTS_MASK I get the following
error:

Gdk-ERROR **: BadValue (integer parameter out of range for operation)
  serial 202 error_code 2 request_code 26 minor_code 0

It turns out that the highest value that passes is 249, like this:

gdk_pointer_grab(myWindow->window, TRUE, 249,
      myWindow->window, NULL, GDK_CURRENT_TIME);

This can't be normal?
