[Bug 622704] [NEW] 18446744059.501920 BUG: unable to handle kernel NULL pointer dereference at null

[Davide Paltrinieri]

Public bug reported:

This problem appears twice and I found it after quitting the
screensaver, so unfortunately I'm not sure what kind of apps could
produced the bug.

The only apps opened was firefox and apparently the os was not doing any
other particular operations.

Hope this can help you to find the bug.
Cheers
