menulibre crashed with TypeError in abspath(): expected str, bytes or os.PathLike object, not bool

[Spass]

I was testing Menu Libre 2.2.0 on newest Xubuntu 18.04, I added a new blank launcher ("Nowy aktywator") in a random folder (Graphics for example), used search field to find it ("nowy"), clicked somewhere on empty space couple times, clicked on disabled (greyed out) menu buttons and at some point Menu Libre crashed with

menulibre crashed with TypeError in abspath(): expected str, bytes or os.PathLike object, not bool

but it remained open, and soon a new instance of Menu Libre showed up also.

Unfortunately I don't have 100% way to reproduce it, but I've managed to crash it couple of times just by playing with it this way. Sometimes it look longer to crash.

I tried to reproduce this error and got a crash. Not with the same message though. ubuntu-bug did not report my crash as a duplicate but I think it may well be: https://bugs.launchpad.net/ubuntu/+source/menulibre/+bug/1767657
