Problems navigating directory listings/opening files

[mottram]

I have Xiki (mostly) working on OS X 10.8.2, installed from the repo, using Aquamacs and Ruby 1.9.3 via rvm.

If I type$ ls and double click, the directory listing appears, but if I try to double click on a listed file or directory I get an error like this:

      - tried to run: proc { |l| Console.launch(:sync => (true)) }
      - error: can't dup NilClass
      - backtrace:
        /Users/jack/src/xiki/lib/xiki/console.rb:394:in `dup'
        /Users/jack/src/xiki/lib/xiki/console.rb:394:in `append_log'
        /Users/jack/src/xiki/lib/xiki/console.rb:383:in `launch'
        /Users/jack/src/xiki/lib/xiki/launcher.rb:513:in `block in init_default_launchers'
        /Users/jack/src/xiki/lib/xiki/launcher.rb:251:in `call'
        /Users/jack/src/xiki/lib/xiki/launcher.rb:251:in `block in launch'
        /Users/jack/src/xiki/lib/xiki/launcher.rb:240:in `each'
        /Users/jack/src/xiki/lib/xiki/launcher.rb:240:in `launch'
        /Users/jack/src/xiki/lib/xiki/launcher.rb:280:in `launch'

I tried installing all the gems listed in the 'Issues Loading Xiki' file (except xiki/cassandra which doesn't seem to exist?) to no avail.

Any ideas?
