Thanks a lot for the reply, Saam. I don't think I'll have time to look into it any further. I'm sorry that the stack trace wasn't of much help. I was hoping there was a chance others could reproduce by running the same command I ran, but I understand that others might not want to install gnome-web-photo and wade through its source code to understand what's going on.
Further, as you said it's possible the bug is already fixed. Again, thanks a lot for your time, Saam!
