That's too bad. As described menus are pretty broken on my machine. And 
I'm still on an LTS distribution (Ubuntu 16.04), which must have a lot 
of users.

None, really. But then again, I have menu-bar-mode turned off most of 
the time.

I've just tried this when working on a feature request to add a menu to 
inf-ruby-mode (third party package).

According to 'M-x debug-on-entry', I don't. Should I check that with GDB 
as well?
