[plist.parse.foundation.failed]: Failed to parse AddOns/keyconfig.plist as a property list using Foundation. Retrying using homebrew parser. WARNING: the homebrew parser is deprecated and will be removed in a future version of Oolite.
Parse failed at line 2 (char 23) - unexpected character (wanted ';' or '}')
[plist.homebrew.parseError]: Property list isn't in XML format, homebrew parser can't help you.
Line 2 is where the funkies appear for the first time. I am pretty sure there is something wrong with those despite them appearing normal. I suggest you edit the file, ensure that you retype the double quotes and save.
