I'm running Kubuntu 14.10 and I am still experiencing the bug. For me it does not seem to be related to suspend/resume, at least it happens long after a resume. Also, there was never a particular high load on the machine. In my case it seems to get triggered by clicking on a link which then gets opened in the Chrome browser, but unfortunately it is not reproducible.
The screen turns black and after some time the login screen appears.
