Comment 2 Pavel Raiskup 2019-08-15 08:15:27 UTC 
The patches from dist-git causing this do not point to any bugzilla
number, nor to any discussion on mailing list:
git diff 02d52503966dfb7194da30059aa16a212bdf0284..fca6f29cc974602845a3b4eaeffa57d5afa32859
Comment 3 Ondrej Dubaj 2019-08-15 08:56:15 UTC 
Sorry for that, the bugzillas of patches causing problems are: 

https://bugzilla.redhat.com/show_bug.cgi?id=1659433

https://bugzilla.redhat.com/show_bug.cgi?id=1666798

The changes in patch described in #1666798 are probably causing crash and it's already reverted in fedora-all
