Oh, so this is yet another example of fallout from the braindead decision to 
enable updates-testing by default for Branched.

And that's the other reason why that decision is broken.

updates-testing should NEVER be on by default. There is no expectation of 
upgrade path in updates-testing (whereas there is one even in Rawhide!), so 
enabling it by default is very broken.
