The code which sends the button events was checking whether there is a focus widget with a button handler but then always sending the button event to the grab widget. If the grab widget is different from the focus widget at this point then it will check the wrong widget for a button handler and potentially crash. It is also possible for there to be no grab widget here in the following situation: 1. Press and hold down the left mouse button 2. Press and hold down the right mouse button 3. Release the left mouse button 4. Release the right mouse button In this case the grab will be released at step 3 because the code only keeps track of the grab for one button. Then it will try to send the release event for the right mouse button to a NULL widget so it will crash.
