ValueError: not enough values to unpack (expected 3, got 1)

After upgrading to python-3.12.7, if there is a pkgcheck.conf, the pkgcheck scan . command will throw an ValueError.

[DEFAULT]
# Disable noisy keywords (checks)
keywords = -PotentialStable,-RedundantVersion

This is my pkgcheck.conf. Deleting pkgcheck.conf or downgrading Python to 3.12.6 resolves the error. I think this issue is similar to the one fixed in #676 .

Expected Behavior

No response

pkgcheck version

pkgcheck 0.10.31

pkgcore version

pkgcore 0.12.28

Fixed in pkgcore/snakeoil@817418d, which would be a fast release of snakeoil 0.10.9. I hope in some minutes to push it to ::gentoo.
