When I press Option + Escape to use the intelligent auto-complete functionality of TextMate, the following is dumped to the file I'm currently editing...

/tmp/temp_textmate.KzzomC:38:in `<main>': undefined method `to_a' for "":String (NoMethodError)

The "KzzomC" string is variable, but the rest is always the same. Does anyone know how to fix this as it would be really good to be able to get this functionality working.
