Hello,

  This looks to me like a conflict between a package you want to install and a package you already have on your computer.

  You probably have to remove openjdk-6-jre-headless (sudo apt-get remove openjdk-6-jre-headless), if you want to have the new package.

Thanks for your reply. Yes, you're right, and I understood as much, too. My point in reporting the bug was, this was a freshly upgraded system, I hadn't even had a chance to mess it up yet. So there might be a little bug somewhere in package dependencies, user shouldn't need to turn to apt-get to fix a freshly upgraded system I think.

No idea if this is significant but subsequent tries to boot into the "netbook" session don't crash anymore - the session just shows an empty screen (apart from the desktop background image).

Also, I just noticed this looks like a duplicate of #1041773.
