This bug seems almost fixed in 0.3.0. 0.3.0 now the '--no-gui' option
which will allow you to run it without an X server. It also attempts to
provide some automatic detection but there is a bug in this line:
https://sources.debian.net/src/qmidinet/0.3.0-1/src/qmidinet.cpp/#L388

Q_WS_X11 is a qt4 constant and is never defined in qt5 so the detection
never works. The nearest constant in qt5 is Q_OS_UNIX, but the code
should then also be modified to detect wayland displays as well (or
maybe there is a QT API to do this portably?)

Jaromír, I noticed you only sent this question to the bug report number
(xxx at b.d.o). Bug submitters are not automatically CCed on bug reports
they submit so if you want to ask the submitter to do something, you
need to CC them manually.
