[TxMt] Errors running Ruby in Textmate

[Jonathan Waddilove]

I have started making use of the 'Run Script' feature for ruby files I'm
editing. All works fine and then I start to get this error:
	/Applications/Tools/TextMate/TextMate.app/Contents/SharedSupport/Bundles/Ruby.tm	bundle/Support/tmruby.rb:115:in `sub': wrong argument type nil
(expected Regexp) (TypeError) from
/Applications/Tools/TextMate/TextMate.app/Contents/SharedSupport/Bundles/Ruby.tm	bundle/Support/tmruby.rb:115

Quitting and restarting TM bypasses the problem, but it would be good to
have it fixed! I'm on OS X 10.4.5, I'm willing to provide more info if
that helps...

Thanks in advance
