2012.04 release prep

Hi there. The 2012.04 toolchain release is this week.

Ulrich, I see your fix for LP: #968766 has been approved upstream. In theory it's too late but I'm happy to land it if you are. Could you decide and let Andrew know by the middle of Tuesday? Andrew, if you don't hear from Ulrich then spin away.

Andrew, could you run the release process on Tuesday please? There's one extra step this month: once you've uploaded and spawned the job, go to the scheduler screen and click on 'Release' beside each of the ursas. I reserved them to make sure they'd be idle and ready to pick up the release build when ready.

Thiago, let us know if Ulrich or I can lend a hand with the GDB release.
