This is a race condition. The window manager gets a request to
deiconify, and then will map your window. However, the window is
probably still unmapped when you do the grab. Remember that X is
asynchronous. If gdk_pointer_grab() is returning GrabNotViewable then
this is almost certainly the problem.
