New issue 371: kallithea 0.6.0 under python3 crashes when the --log-file option is selected
https://bitbucket.org/conservancy/kallithea/issues/371/kallithea-060-under-python3-crashes-when

Chris Rule:

If I start kallithea 0.6.0 stable with the --log-file option \(“--log-file=/opt/kallithea/kallithea.log”\), the log file is created but contains a series of gearbox errors \(see below and attached\). Without the --log-file option, the logs go to /var/log/syslog and appear to run correctly.

Logfile:
