Crash when trying to change staff properties
Under linuxmint I get reproducable a crash when opening note line properties and press OK. So it is not possible to change anything in that respect (note heads, tuning of tablature etc.).
Open a new score, open the note line properties dialogue and press OK.
Then musescore crashes.
This bug I get in with the latest nightlies (from 31.12. appimage, self compiled from today caff127 ).
