Comparing with the working UBUNTY_MENUPROXY=0 instance, you can see that some sub-menu filled dynamically are all with their minimal menu list (static items I guess) almost empty
For instance menu "File/New" should contain 18 menus items above "others". If you select "others" nothing appear except, maybe, a crash
menu "window/view" more than 15 menu choices and nothing appear when you select others.
Same version than you 64bits
