I've found the bug and reported the fix upstream.
Implicit pointer grab release was broken in GTK+2. It was not releasing implicit pointer grabs when modifiers like NumLock were active at the moment the button was released. The behaviour described in this bug was a side effect of this. You can see this by trying to reproduce without numlock on.
