Thanks, Nicolas.

Fwiw, it was first reported in gstreamer and suggested to report to
pygobject, see here


Your example is helpful but I am not sure that it actually addresses all of
the cases that previously worked, unfortunately.  Our workaround is much
more extensive at this point than just adding a .to list() for every case
with array like properties and it used to be much easier.  I will follow up
when I can, but it sounds like there is no intention to restore the
previous behavior?  That is useful for our planning.
