TC3.1 machine. No missing dependencies.
EmelFM2 is configured to show ~ in Pane 1 and /mnt in Pane 2. Pre update this worked OK as a non-superuser. Following the update, it is no longer possible to navigate away from these directories.
Re-setting the opening defaults to show / in Pane 1 and / in Pane 2 then restarting EmelFM2, browsing is again possible.
Using EmelFM2 as superuser works OK.
