Comment 4 for bug 904275

I've noted that the code in the fix for bug 770263 has a comment:

"Some apps (notably Eclipse RCP apps) don't fill contents of submenus until the menu is shown. So we fake that by toggling the visibility of any submenus we come across. Further, these apps need it done with a delay while they finish initializing, so we put the call in the idle queue."

It may be that due to the wait for the sub-menus to initialise there is a timing/race and clicking on that area causes the crash? and/or that as a consequence the menus do not order correctly.
