Bug 44184

У Ardour какие-то проблемы с парсингом тем Gtk2, он виснет при запуске. На полностью обновленной ALW p10 это проявляется так:

```
$ dconf reset -f /org/mate/marco/
$ gsettings list-recursively | grep "mate.*theme"
org.mate.NotificationDaemon theme 'coco'
org.mate.interface icon-theme 'menta'
org.mate.interface gtk-theme 'Menta'
org.mate.interface gtk-key-theme 'Default'
org.mate.file-views icon-theme 'crux_teal'
org.mate.peripherals-mouse cursor-theme 'mate-black'
org.mate.Marco.general theme 'Dopple'
org.mate.lockdown disable-theme-settings false
org.mate.control-center.appearance more-themes-url 'http://mate-desktop.org/themes/'
org.mate.screensaver themes ['screensavers-footlogo-floaters']
org.mate.screensaver lock-dialog-theme 'default'
org.mate.sound theme-name 'freedesktop'
$ ardour6

```

и дальше ничего не происходит. Главное окно Ardour не появляется.


Решение есть в ветке https://bbs.archlinux.org/viewtopic.php?pid=1939167#p1939167 - запуск с передачей пустой переменной GTK2_RC_FILES позволяет нормально запускать Ardour:

```
GTK2_RC_FILES= ardour7
GTK2_RC_FILES= ardour6
```
