Segfault with _sync() methods on python 3.11

[elParaguayo]

I'm trying to add python 3.11 to run the tests for Qtile on github.

A couple of our tests in qtile use the sync methods of dbus_next and these fail under 3.11.

Digging in to this some more, it seems that any _sync method triggers this.

For example, running the example at https://github.com/altdesktop/python-dbus-next/blob/master/examples/glib-list-names.py triggers the same segfault.

EDIT: I wonder if this is actually a fault in the glib mainloop. Let me test a bit more.
EDIT 2: No. Basic MainLoop examples run ok on python 3.11.

OK. It looks like this is an issue in v0.2.3 but is working in the latest git master.

Any chance of pushing a new release?

[AiyionPrime]

She solved my problem by specifying a commit from main.

Any chance of pushing a new release?

Would be highly appreciated.

[dreirund]

I still see that this is unresolved in release, but resolved in latest git.

What hinders making a new release, so that distributions can pick up?

@altdesktop

Sadly, I think it's pretty safe to say this package is no longer maintained.
