wrote a feedback on their site about this, i hope it gets fixed in the next release! i also discovered that sometimes the GVM desktop would say "can't connect to GVM" while refreshing the app list. i found out the refresh fails when metalayer-crawler (don't you just love it?!) is doing its thing.

what i do is just go to tools - clean icons until it refreshes successfully.

still, the backup script would be our safest fallback. hope someone makes it or at least teach us how to manually do it ourselves
