Did the ownership of /tmp change? I would expect that directory to be
owned by root. I'm unable to reproduce this failure on my sid test vm
(where /tmp is owned by root and permissioned 1777). But I can
reproduce it if I chown /tmp to bin or somesuch.
The failed tests show this error which munged logs before exiting:
> munged: Error: Logfile is insecure: invalid ownership of "/tmp"
The preconditions for that error are here:

It tests for the directory to be owned by either root or the process euid.
