BUG: Bad page map in process indicator-appli pte:7c79010208000000 pmd:00050067
No idea what triggered this. EDIT: I failed at reporting this bug clearly. Please read the comments first, then you can read the rest of this description if you like.
20 seconds prior to the BUG, you'll see a SaK in the kernel logs (Secure Attention Key, aka "please kill everything on this vt, and let init/kdm give me a new login screen". This is legitimate. I invoked it due to software issues which were not obviously kernel related. I am able to reproduce the software issues, but they don't trigger the BUG, and I haven't been able to reproduce the BUG at so far.
Software issue: blowing away all your dotfiles and dotdirectories seems to leave you with a panel-less, dock-less desktop. So that's what I was using SaK to get out of. (I think ctrl+alt+del would have worked, but it wouldn't have given me a "log out" option, only a "shutdown" option). Behavior I was expecting: GNOME should recreate dotfiles with default settings. But that wasn't actually a new bug; it had just defaulted to Unity, which doesn't quite work on my installation. So I'm not complaining about that at all.
