Hi,
on a completely(!) fresh Manjaro installation with latest updates using GNOME my nextcloud-client wont show me the GUI, once I start it manually from within the menu, the terminal or even automatically at startup. But synchronization works fine.
In order to see the GUI and be able to use it, I need to kill the first start of the client (see above) manually!! Then I need to restart it and the GUI shows up.
I highly doubt that this is normal behaviour. 
Does anybody have any idea what the underlying problem might be and how to solve it?
Many thanks!
