Puddletag fails to start after upgrading pyparsing to 3.1.2

[k0mmsussert0d]

Current Behavior

Pyparsing crashes during the start-up. Following output is printed:

puddletag Version: 2.3.0

Downgrading pyparsing to 3.1.1 resolves the issue.

Expected Behavior

Puddletag should start normally with installed dependencies as provided in requirements.txt file.

Steps To Reproduce

1. Attempt to run puddletag

Information about your system

Puddletag: 2.3.0
OS: Arch Linux x86_64 (6.7.9-arch1-1)
Python: 3.11.8
PyQt: 5.15.10

Anything else?

Technically a duplicate of #876, but I will leave this open until #880 is merged.

[Arnvidr]

Can confirm that #880 seems to fix it for me. pyparsing has also fixed this upstream, if there's a 3.1.3 version in the near future.

[vinivosh]

Can confirm the cause too. Downgrading pyparsing to 3.1.1 has fixed the Puddletag crash on startup.

I am on Arch and after upgrading the puddletag-git aur-package to the latest version, it works fine again.

I am on Arch and after upgrading the puddletag-git aur-package to the latest version, it works fine again.

Only because the AUR package includes/applies PR #880.
