Ah, gotcha. Yes, that's 1.3.0, SRPM version 1. We didn't make up
this nomenclature. :-(

Ok. 1.3.x is much mo' betta' then 1.2 in many ways. We could
probably help track down the problem, but if you're willing to upgrade
to 1.3.x, it'll hopefully just make the problem go away.

Can you try a 1.3.1 nightly tarball?
