Bug#874598: ardour: GUI doesn't load

[Ivan Stana]

Package: ardour
Version: 1:5.11.0-1
Severity: important

Dear Maintainer,

When I want to run ardour5, it gets stuck and GUI doesn't load at all. CPU utilization is 100%.

I wiped ~/.config/ardour5 directory, tried to start jack server separately, installed gtk2 murrine theme
and waited about 30 minutes and search internet a bit, but no luck.

$ ardour5
