I agree totally, but for that
- I'd have to understand exactly what the addTitle does that makes Qt/Mac crash
- Ideally I'd also know how to determine if the menu is in the global menubar or e.g. in a popup menu, where addTitle works perfectly fine. I think we'd want to preserve that because popup menus follow the selected style and not necessarily the OS X style.
There's also the point that the addTitle (and addSection, IIRC) in Qt5 don't crash. They have other issues (IIRC you get just a separator, not the title text) but until now I've preferred to handle these crashes on a case-by-case basis.
I admit, this RR was also made a bit with the idea of getting a discussion going about this issue. ;)
