Comment (by boonebgorges):

 Whoops. Sorry about the debacle.

 To be more specific, the `$blog_id` parameter was broken only when not
 combined with one of the 'role' parameters. [attachment:22212.diff] fixes
 this by doing a key-only lookup (which will match any role) when no role
 has been specified. There's also a unit test in there.

 Feeling a tad gun-shy, so I'd appreciate a look from one of my esteemed
 colleagues.
