Comment 3 for bug 1658776

I also experienced this bug in Ubuntu MATE 17.04. When using the "Mutiny" layout, several apps crashed as soon as I clicked on an entry in the menubar. All the apps that crash have in common, that they display the menubar not inside the application window but at the top left of the screen aka "global menu" (e.g. Caja or Eclipse). But surprisingly Gimp works as expected even though it also uses the global menu.

This bug is also described at https://ubuntu-mate.community/t/ubuntu-mate-16-10-top-menu-crashes-all-the-time/10896 and it seems to be a duplicate of this bug: https://bugs.launchpad.net/ubuntu/+source/topmenu-gtk/+bug/1630515
