Camera settings drop-down boxes not updated when webcam attached or removed

Under Settings->Media, the drop-down boxes for Camera Settings, where resolution etc is selected, stays blank and disabled even when camera device has been attached.

To reproduce:

  • Start dring and jami-gnome with no camera device attached to system.
  • Attach webcam.
  • Go to Settings->Media. The drop-down boxes remain empty and greyed-out even though live video preview is shown.

Also:

  • Start dring and jami-gnome with webcam attached.
  • Unplug webcam.
  • Go to Settings->Media. The drop-down boxes shows old video device info.

System info:

$ /usr/lib/ring/dring --version Jami Daemon 9.1.0, by Savoir-faire Linux 2004-2019 https://jami.net/ [Video support enabled]

$ jami-gnome --version 74ef874e - unknown (About page says "Free as in Freedom" built on 2020-04-14 20:24:50 UTC)

OS: Xubuntu 18.04 with kernel 5.5.17

This is reproducible also on Xubuntu 20.04 beta with Jami Daemon 7.4.0/jami-gnome "Live Free or Die" built on 2020-03-23 06:24:58.

As an aside, I once got a dring segfault in relation to this, but unfortunately I cannot reproduce that bug. Just FYI, here's the log of that one occurrance (as much of it as I have):
