I managed to produce a stacktrace. Hopefully this, combined with the
stacktrace
at the end is sufficient to solve the issue.

As I've made some bug fixes for the Menueditor last time, I tried to
reproduce this error. Till now I wasn't able to reproduce it on Lazarus
Trunk revision 54826 with FPC 3.0.2 on Windows 7, 10, OpenSuse 42.2 KDE
GTK2 or Linux Mint 17.3 KDE GTK2. I currently install on a VM a 64bit
Linux Mint 18.1 Cinnamon (your OS?!), to test the issue there.
I'll report.
