@chillinger thanks for the patch. Can you explain where it failed? The tests passed in the past so probably a test is missing somewhere.

It looks like I forgot to make this uniform, the title is just missing the underscores and this will break the regex.
EDIT: can you please add the following: key => 'log_directory',
