I'm using libsolv via the python bindings and am hitting a segfault when
performing problem resolution.

This is using a custom build of rpm (4.17.0) and libsolv (0.7.20) to verify the
issue persists with the latest version but I can reproduce this with
rpm/libsolv as shipped by Leap 15.2 as well.

This happens when calling element.Job() on the list of solution elements.

relevant pysolv part:
