`pik config` fails: undefined method + for nil:NilClass

[klauern]

I don't have anything special that I know of in my OS (WinXP):

PS C:\mydocs> pik config
** CURRENT CONFIGURATION **


There was an error.
 Error: undefined method `+' for nil:NilClass

  in: pik/commands/config_command.rb:42:in `list'
  in: pik/commands/config_command.rb:11:in `execute'
