Comment 10 for bug 347768

Here's the news.

I've landed a branch that extracts logic out of soyuz for permission checking. It was a time-consuming, unanticipated chunk of work. The function now lives in lp.archiveuploader.permission.

The linked branch has a set of unit tests for this change. One of the unit tests fails -- that's the one you need to make pass to fix this bug.
