In straces everything seems to spin on:
python3 3736 paelzer 3u unix 0xffff8fe4a2ba5000 0t0
2092674 type=STREAM
But that might just be GTK refreshs or such.
Yep that is only
u_str ESTAB 0 0
@/tmp/.X11-unix/X0
2091383 * 2092674
I'd need to see how to debug the actual resolve call.
PkgProblemResolverResolve of python-apt-1.7.0~rc1/python/depcache.cc is the
implementation of this.
So fra trying to py-* in gdb's python support didn't grant me a lot useful
things :-/
While still hanging in that resolve call threads look like this:

Thread 3+4 are of GTK and seem not interesting.
Thread 1 is pythin, but it seems to spin in Gtk.main()
(gdb) py-bt-full
#11 Frame 0xb6bc78, for file /usr/bin/update-manager, line 118, in <module> ()
Gtk.main()
(gdb) py-list
113 settings.set_int64("launch-time", int(time.time()))
114 init_proxy(settings)
115
116 app = UpdateManager(data_dir, options)
117 app.start_update()
>118 Gtk.main()
That is not where the resolver is stuck.
Which leaves Thread 2
2 Thread 0x7feac9396700 (LWP 3737) "dconf worker" 0x00007feada28dbf9 in

But I'm not sure if this is the right thread, it doesn't seem to by
python more like Gnome-Settings related.
I'm not an cpython debug expert at all, but would want to know what to
look further before the situation resolves and I can't check it anymore.
