> Top group 2012 =  2011, 2010, 2009, 2008, 2007, WINTER

Your usage of "Top group" is strange. Top groups should only be used for independent groups of logbooks, more like you were running one dedicated sever fore 
a group of logbooks. Further, you defined logbooks (2008, 2009, ...) which do not exist in your config. Why don't you just remove the "Top group" line from your 
config? If you want to group different logbooks, just use the "group" command as written in the docs.
