[Bug] Crash trying to load locally saved queue after removing catalogs on Ampache server #507
Description
Should be self-explanatory, Supersonic will crash trying to load previously saved (local) queue of tracks upon starting. This started happened after I did some re-arrangement of catalogs on Ampache server (I removed some of them in order to split them and added it back as multiple catalogs).
This can be fixed (until next such incident) by removing $HOME/.var/app/io.github.dweymouth.supersonicconfig/supersonic/saved-queue.json.
Here's the stdout of me trying to run Supersonic with saved-queue.json still intact and thus experiencing a crash:
