Reboot / Restart OctoPrint issue

[PtrJns79]

Using Version: 1.2.0-dev-586-ge482e95 (mrbeam-stable branch)
As reported by the web interface...

Selecting "reboot" from the power button in the header, does seem to reboot the device (ssh session shows > 2015-03-18 20:26:12,016 - octoprint.server.api - INFO - Performing command: sudo shutdown -r now ) but when the web interface comes back up, the last screen to re-opens and still shows the last slicing process as still running.

CTRL-F5 (windows machine) will reload the page and prompt with the laser warning message.

Selecting Restart OctoPrint does seem to restart octoprint but produces a popup/error message in the top right of the screen

"Error
The command "Restart OctoPrint" could not be executed.
More
503 Service Unavailable
No server is available to handle this request."

Last open page is displayed and last working slice etc displayed until CTRL-F5

SSH outputs the following:
