This means the deltarpm didn't build back into a byte-for-byte copy of the original rpm. I've just applied the deltarpm above against the original -0.9.20110509 rpm in the repositories, and there are no errors, so that seems to mean you had a bit-flip either in memory or on the hard drive. If you can reproduce the error (by downgrading mesa-dri-llvmcore and then updating again), I'll happily take a look again. Otherwise, I'll close this in a week or so.
Sorry, Andre, I just saw that you canceled the needinfo on this. Have you seen this bug on one of your systems?
I didn't deliberately cancel the needinfo, just subscribed to the bug. Sorry about that.
Closing as it seems this was a one-time fluke. Please reopen if you hit this again.
