You can log bugs for it against the yum-utils package, and/or talk about it on
the yum-devel mailing list. Saying that, I probably know the most about it so
you'll probably end up with me anyway :).
It's been a long time since I looked at this plugin and I didn't write it, but
that bit does look wrong (it looks like it'll try and search for any package
that is removed, after it is removed) ... although it's been around for a few
years now, so if it's wrong as it looks I'm surprised nobody has seen it
earlier :-o.
Assuming that is the problem, it's possible that we are removing a cache
sooner now in yum ... so before the plugin was getting the
(cached) old rpmdb entry (from before the transaction happened) and now we've
wiped that it's failing. Or maybe more likely the po.state should be updating
to REMOVED and isn't anymore.
My guess is it's trying to do some optimization so that accessing
thispo.filelist doesn't trigger a filelist metadata download.
Can you confirm that it's looking for the package that is being removed?
If you turn off post transaction actions is the package remove failing in
anyway?
