It has been some time since I suggested this, but as far as I remember
I looked into this because I had quite a few crashes. They seemed to
be related to menus.

Yes, correct. And I pointed to another place where I thought the
problem was instead.

Since you asked for a recipe I thought I had to mention this again. It
looked to me that you overlooked this problem again.

Did you look at the logic as I suggested? If you are sure my
suggestion is wrong then feel free to close the bug.
