Bug 549712 failed to fix or apparently understand the problem, despite a working patch as an example. 1. Closing the Customize dialog with a cancel or deletion or otherwise non selection to carry forward results in the menulist selecting the nonsensical and invalid "Customize..." item. 2. The filter is then allowed to be saved with this invalid value, creating a broken filter. 3. Attempting to edit such a filter again results in unexpected behavior. Using a menulist's menuitem as a window opening option is abuse of menulist, but ok. However, such an invalid menuitem cannot ever be a selected value.

Yes, I can reproduce the problem. Do you want to fix it or should I?

Would this suffice?
