start from qdbus
Happens in Fedora 31 beta when launching any qt application from qdbus. This happens for example when opening a folder in dolphin from a flatpak application, the dolphin window will be unthemed. Also happens when launching dolphin by selecting a filesystem folder that exists on your system from krunner. Launching dolphin normally does not cause this issue.
That said, this almost certainly isn't a spectacle issue (ie, problem lies elsewhere). One possibility: dbus-activated applications may not inherit (all? any?) user environment variables
This bug shipped with Fedora 31. Launching from the KDE Application Menu causes it to lose theme, so it's very easy to run into.
