when a user has one or more running processes the system will refuse to delete that user (rightfully so). however, user-manager apparently has no GUI backing for this case which results in no visual feedback at all. Reproducible: Always Steps to Reproduce: 1. create user 2. login on tty and run top 3. try to delete user Actual Results: polkit auth comes up and then nothing happens Expected Results: should throw an error that $user has shit running and possibly even offer to kill all running processes or bring up ksysguard or somesuch business.
