puddletag: starting fails with TypeError

[antonmosich]

Describe the bug

Puddletag fails to start properly and fails with a python error message instead of starting. See Additional context for the Traceback.

Steps To Reproduce

Steps to reproduce the behavior:

1. nix run nixpkgs#puddletag or nix-shell -p puddletag --run puddletag or something like that. You need to have a graphical environment.

Expected behavior

I expected puddletag to start and present its GUI

Hm, I can reproduce, and I am pretty sure this is related to and fixed by #300887 which fixes an issue with pyparsing.

[peterhoeg]

Yep the referenced PR fixes this.
