Dear Maintainer,

I appear to be running into the same/similar problem.

When using nheko with:
  * i3 window manager on X
  * pipewire with wireplumber session manager

As soon as I attempt to place a video call, I get a segfault. However,
text chat and voice chat work perfectly. I have attached a stack trace
to this report.

Sincerely,

Nathan
