This happens when opening any SRPM that was created with a user
account that doesn't exist on the target machine.  (And will probably
happen every time w/mock because no users exist in the chroot it
makes.)  IIUC, RPM stores the owner and permission of all files
included in an SRPM when building it, and then tries to restore them
when it's installed.  If it doesn't exist, it prints that warning and
falls back on a default value.

It's completely harmless.

I think that's just a coincidence.  What error do you get when running that?
