Anything else? #

It might have something to do that QueryTree fails in the Java context, see the log journalctl log output.

When running xdg-open directly from the shell it works:

xdg-open "file:///home/julian/foo/"

Revealing via dbus works as expected.

Workaround

This bug only affects revealing the vault. It will be unlocked and can otherwise be used without any problems.
