distro info bails out and prevents work from getting done when it doesn't have to

$ pbuilder-dist raring login

distro_info.DistroDataOutdated: Distribution data outdated.

This is really ridiculous. Yes, it's outdated, but the data it has knows about raring, so there's no need to bail out like that. The package should only error out in cases where it can't continue. A traceback is a very poor raw to communicate a need for a package udpate.
