backintime-qt4 hangs. Command line backintime suggests cannot unmount encfs

[Christopher Barrington-Leigh]

backintime-qt4 fails to backup, and/or hangs on startup.

There's no error information, it seems.

But using the command line, I get:

$ backintime unmount --profile Primary
INFO: Mountpoint /home/meuser/.local/share/backintime/mnt/xxx1/mountpoint is already mounted
INFO: Mountpoint /home/meuser/.local/share/backintime/mnt/xxx2/mountpoint is already mounted

Please re-open and report back if you can reproduce the problem with the latest upstream(!) version Back In Time.

Be aware that the latest version (1.3.3-4) in Ubuntu is out dated.
