Icon theme not remembered, reverting to default icon theme at each relaunch
I'm using the default Kadu version in openSuse Leap 15.0 (v4.3) and I would like to have the 'faenza' icons as my default icons. But each time I change them via Kadu -> Preferences -> Look -> Icon theme, they are used for the current session, but get forgotten if I quit Kadu. When I run it again, the default icon theme is used. I've changed other preferences, and they seem to be remembered without problem, only the icon theme is not remembered.
Is there something I can do to solve this issue, or is it a bug that needs a correction in the code?
Thanks!
