Good.

So there is likely a difference in the python-rpm binding implementation. I'm
not surprised ...

Try to pin down the exact return code in yum/anaconda that is failing.
One way to do this is to turn on RPMIO debugging, another way is
with strace (limit to open/close/read/write if the spewage overwhelms)

(from ancient memories)
The @rpm5.org code has a slightly different return for EOF than what
yum/anaconda are expecting. Just one guess ...

... another guess ... the @rpm.org python bindings is trying to support
reading headers without verifying digest/signature, and is also (though
its enturely unused afaik) attemptint to support multiple concatenated
headers read from single file.
