I did a fresh install of 12.2 a couple days ago, and I’ve had a lot of issues with Banshee crashing. I haven’t been able to narrow down an exact cause, but it often crashes when saving metadata or switching to Idle after finishing a song. It looks like it might be related to this bug, since I have the same version of gconf installed that’s mentioned there.
While it’s a fresh install, I mounted to my pre-existing /home partition, so it’s possible that there are still some configuration files causing it to crash, though I don’t know why that would be the case.
Looks like I’m switching to Rhythmbox for the time being…
