Cause: Previously there was an typo in the tuned-adm code regarding automatic daemon restart. Consequence: If tuned-adm command was run and if it found out that tuned daemon is not running, it tried to restart it, but this attempt failed with the traceback. If tuned daemon was running (the default, expected state), everything worked as expected. Also daemon restarts through systemd worked as expected. Fix: The tuned-adm code was fixed. Result: Now the tuned daemon restart attempt performed by tuned-adm doesn't end with traceback.
There is traceback during profile selection if service tuned is inactive.

It's already fixed in upstream commit: https://git.fedorahosted.org/cgit/tuned.git/commit/?id=7b4596ba21893f12181630d73d6ec99f447104bc
