I've been using Ubuntu MATE for some time. I recently switched to Ubuntu (Gnome 3), and didn't stay long. I've re-installed Ubuntu MATE 21.10, and I'm having problems editing the Brisk menu. In the menu editor, when I try to add a menu item, the menu editor disappears. Checking the logs, I see this:
Mar 7 14:39:42 kernel: [ 4482.746683] mozo[65703]: segfault at 0 ip 00007f177c1efb07 sp 00007ffdf7782498 error 6 in libmate-menu.so.2.4.9[7f177c1ec000+d000]
I had no issues with the menu editor in my previous install.
