[Bug 643932] [NEW] crash to blinking cursor when running on battery power

[leighman]

Public bug reported:

Seems to have happened after upgrade to Maverick.
After a short period on battery power the desktop will crash to a black screen with blinking cursor in the top right.
Must hold down power button to turn off. After restart the problem repeats unless the power lead is plugged in.
