Nobody else has reported this. If it is still reproducible, please see http://ardour.org/debugging_ardour for instructions on how to get a useful debug backtrace (the output above is not useful, unfortunately.

I have reproduced this also on openSUSE Leap 15.2 with Ardour 6.0.0.

Steps to reproduce are:
1. start new / empty session
2. add an audio track
3. record a bit of audio
4. delete or split the resulting region (delete or split cause the crash for me)

I believe the crash is triggered in the following block of EditorRegions::region_changed

        boost::shared_ptr<ARDOUR::Playlist> pl = r->playlist ();
        if (!(pl && _session && _session->playlist_is_active (pl))) {
                /* this region is not on an active playlist
                 * maybe it got deleted, or whatever */
                if (map_it != region_row_map.end ()) {
                        region_row_map.erase (map_it);
                        _model->erase (map_it->second);
                }
                return;
        }

which is failing the following assert in TreeModel::iterator TreeStore::erase of gtkmm

  g_assert(iter.get_gobject_if_not_end() != 0);

Attaching the backtrace

Since I can't reproduce this with openSUSE Tumbleweed, I'm guessing we are hitting a bug with another library. I tried updating glib to the version in Tumbleweed, but that didn't help. Trying to build Ardour now using the boost libs from Tumbleweed so see if that helps. I'm not that experienced debugging c/c++ so perhaps I'm barking up the wrong tree.
