Can't establish call between two Dino instances

[JulienPalard]

One is dino-im 0.4.3-2 on a Debian Trixie, the other one is a dino-im 0.4.2-1 on a Debian Bookworm.

I'm on the Trixie one.

When we call each other, dependless on which calls who, we're getting a "call has been rejected" notification even though we're accepting it.

We're in a one-to-one conversation encrypted using omemo.

What seems relevant in my logs:

May 01 16:52:01 zhakar dino-im[3014]: file ./plugins/rtp/src/video_widget.vala: line 235: uncaught error: pas de propriété « name » dans l’élément « videoconvert » (gst_parse_error, 2)

On the other one the "phone" button to establish calls is sometimes greyed out (but I don't have logs from this machine yet).

Other lines that may or may not be of interest:
