Unable to update Rawhide

[Adam Huffman <bloch verdurin com>]

At the moment I'm unable to update my Rawhide laptop.

It seems to be an rpm rather than yum problem, because the same thing
happens if I try to update packages manually.  Here's a typical attempt
with yum:

  Updating       : setroubleshoot

- it's the same for all the packages.
