Hi Ian,

not sure this helps, but I had similar problems when upgrading TS
until I moved all my plugins to the corresponding gems.
Seems like load-order may introduce subtle abnormalities for certain
plugins/gems.

For example, try installing acts_as_state_machine as a gem and put TS
last in your environment.rb.

Also, don't forget to adjust your config.gem-line after upgrading to
something like this (like mentioned in the ts-upgrading instructions):

[...]
   config.gem(
             'thinking-sphinx',
             :lib     => 'thinking_sphinx',
             :version => '~> 1.3.8'
             )
[...]

Hope this helps,

Claus
