muse-sounds-manager on Linux dies saying "Default font family name can't be null or empty."
Both Muse-hub and the renamed version muse-sounds-manager fail on my system (Ubuntu LTS, xhdpi, xfce) with the enigmatic "Default font family name can't be null or empty." I thought the bug might get fixed, but I guess it's "works for me".
I've tried strace, downloading microsoft core fonts, setting those font families as default, LC_ALL=C and LANG=C and the stubborn thing doesn't budge. There's no reason: it simply doesn't work.
Is there a work-around or a fix? Is there source code to implement the fix suggested on the Avalon UI forums?

Comments
This bug has a fix (possibly a poor fix) in the framework code:
https://github.com/AvaloniaUI/Avalonia/pull/12817
It might be better to report this to the Muse Hub team: https://support.musehub.com/hc/en-gb/requests/new

And while you have them, maybe ask when we can expect the updated sounds, sampler and sounds manager.
