Segfault trying to open Output devices

[C0rn3j]

Flatpak pwvucontrol.
Was clicking on the Output devices tabs to switch to it, instacrash.
After switching from and between recording/input/output tab and config, turning my BT headset from LDAC to mSBC and back.

Can't reproduce.

Side note, Flatpak debug docs are bad as the recommended command will try to download 7GB+ for aarch64 SDK and also the x32 SDK...

I simply did it myself:

flatpak install org.gnome.Sdk
flatpak install com.saivert.pwvucontrol.Debug
