I'd say this is rpmdb indexes fallen out of sync or something like that. Try doing 'rpmdb --rebuilddb' to see if it goes away.

I feel like this should be caught by rpm instead of just segfaulting.
libdnf used to be broken... Should be fixed now.
This is a case of rpmdb indexes going out of sync due to an earlier problem (kill -9 / crash / whatever) and rpm not detecting / cleanly handling that, not a libdnf problem.
...but IIRC there is/was a specific bug for that someplace, which would be more useful than a random segfault on something, so maybe we just leave this closed.
