Test occurring after every Rails command


I’ve got a bit of a strange problem. It’s been happening for a while,
but it wasn’t causing any problems, so I put it to the back burner.

After every Rails command, I seem to get the output of a blank test
immediately following.

For example:

tom@tom-desktop-linux:~/code/workspace/mainsite$ ./script/about
About your application’s environment
Ruby version 1.8.4 (i486-linux)
RubyGems version 0.9.2
Rails version 1.2.2
Active Record version 1.15.2
Action Pack version 1.13.2
Action Web Service version 1.2.2
Action Mailer version 1.3.2
Active Support version 1.4.1
Application root /home/tom/code/workspace/mainsite
Environment development
Database adapter mysql
Database schema version 21
Loaded suite ./script/about

Finished in 0.000416 seconds.

0 tests, 0 assertions, 0 failures, 0 errors

And the same happens with ./script/runner and ./script/server (but
only Webrick). It seems like it executes a blank rake test. I’ve not
changed anything inside these files, so I can only imagine I’ve
managed to wrap rake into something strange like boot.rb or
environment.rb - but these look totally sensible and nothing obvious
is in there!

Any suggestions to help me track this one down?
