There are new upstream releases available, and the package should be updated. Reproducible: Always
Why does the bug depend on dev-python/pika? Is that a new dependency in the new version?
Yes, the current version has sort of a plugin to publish events via MQTT. I have not really tried but think one would only see a problem if one actually flips a few config switches. Currently i would say it is a dep, once an upstream bug is resolved it will be an optfeature. Thinking about it, i could maybe bump with optfeature. But the current version would crash if pika is not there but mqtt enabled. https://github.com/Kozea/Radicale/issues/1490 But wether dep or optfeature, i can not really test is without having a pika on 3.12.
I think i will contribute to upstream radicale to make that dep go away. The current version can probably be packaged by not installing the hook and patching a comment into the config template hooks section. "Not supported on gentoo currently, see this bug" So we can move on here and see what happens to pika.
