Is it a bug or feature that no enviroment variables (most notably
$PATH) are set for DBus-activated KAuth helpers?
Manually launching the helper from a shell doesn't lead to this
behaviour: enviroment variables are properly set.

KAuth helpers are always triggered by DBus, so they follow DBus activation's paradigm.
Besides that, no environment variables should be relevant to an helper, and can instead be harmful, so you can indeed consider that a feature.
