apport bug details for #1763273 (radeon crash while screen blank)

[RBL Admin]

Unfortunately, I had to create a second bug report because apport-collect will not accept a different set of Launchpad user credentials from those I used to create the original bug report (#1763273). My apologies, but I had to use a different Launchpad account to run apport-bug, so this is the result.

When I get home I'll copy these attachments and data into the original bug report under my personal Launchpad account.
