Since rev 19332 the original bug has been fixed. There's still a problem, but it doesn't seem related to menus.

I spoke with the Beezer developer, and it looks like Beezer deletes the BPopUpMenu. Since the BPopUpMenu auto destroys itself, this leads to a segment violation (freeing already freed memory). I don't know why this doesn't happen under beos, but it's a Beezer bug. Closing.
I talked with the author, looks like that BPopUpMenu uses SetAsyncAutoDestruct(true) and it's opened with Go() synchronously. I think this case needs to be reviewed in our implementation. Another problem could be related to archiving/unarchiving.
