It isn’t broken on non-Qubes-Whonix, and it fixes a possible security hole on both Qubes-Whonix and non-Qubes-Whonix. (I think in this instance it was pushed to the stable repo despite the Qubes-Whonix issue due to an oversight, though on Qubes-Whonix it doesn’t make the situation much worse than it was previously.)
As a temporary workaround while we’re getting a fix upstreamed:
- After launching a Whonix-Workstation VM, open a terminal.
- Run
dbus-update-activation-environment --systemd --all && systemctl --user restart fm-shim.servicein the terminal. - The “Open in folder” button in Tor Browser and other apps should now open pcmanfm-qt as expected, until the VM is rebooted.
We’ll update this thread once an upstream PR is filed to fix this.
