[Bug 1530500] [NEW] Desktop manager crashes to login screen without warning

 

Public bug reported:

I would be happy to try to acquire more information to help track this
problem down but I do not know what to do on my own so I would need
directions.

This problem first started occurring after I upgraded to 15.10 and has
been happening once every few days since then. The system will without
warning crash to a console-looking screen which shows some of the
typical startup screen notifications about different services coming up
etc. The system automatically then goes back to the login screen after
about 10 seconds without user intervention. I log in and it seems that
everything works fine but anything I was working on is lost and there is
an error notification waiting for me.
