Testing / feedback request: DNF 3 crashes

Hi folks!

Around the time DNF 3 landed in Rawhide (hence F29), we had quite a few
folks on these lists reporting issues, including crasher bugs. Many of
these seemed somehow related to the DNF history database. They also
were not easy to isolate and fix.

We're now close to the F29 Beta release, but we don't have a great
sense of how many people are still having these problems with DNF 3.2
or 3.3.

Can anyone who is still struggling with DNF crashes on *basic*
operations on F29 or Rawhide please reply, and provide a few details on
what you're seeing and any workarounds or fixes you've found?

Thanks a lot!
