New question #289467 on Epoptes:
https://answers.launchpad.net/epoptes/+question/289467
I have epoptes-server installed on a Ubuntu 14.04 headless server and run
'epoptes' using ssh x-forwarding. Everything has worked perfectly, up to and
including version 0.5.7 (the default in 14.04 repos). As soon as I use the PPA
to update it to the latest (now 0.5.10, but also .8 and .9) on the server, it
works well until a client disconnects (logs out or reboots). Then the GUI
throws an error - 'Lost connection - Make sure server is running' and the
related ssh terminal shows the following Traceback:

I then have to re-run Epoptes and this just keeps repeating, until I downgrade
it back to 0.5.7. This all happens regardless of the version on the clients,
which are Xubuntu 14.04 installations, now with client 0.5.10.
Looking at the errors, is there a dependency missing related to notifications?
