[TYPO3-mvc] Strange warning "You should never see it"

[Dawid Pacholczyk]

Hi guys,
  I have some sick problems.

I`ve just created simple extbase based extension. I`ve created 2 tables 
- connected tham m:n

I didn`t change nothing in code. I mean atm I`m working with files 100% 
generated by extbase_kickstarter

I get nothing in my listAction

when I used var_dump($records) I receive

object(Tx_Extbase_Persistence_QueryResult)[112]
   private 'warning' => string 'You should never see this warning. If 
you do, you probably used PHP array functions like current() on the 
Tx_Extbase_Persistence_QueryResult. To retrieve the first result, you 
can use the getFirst() method.' (length=206)
   protected 'dataMapper' =>
     object(Tx_Extbase_Persistence_Mapper_DataMapper)[45]
       protected 'identityMap' =>
         object(Tx_Extbase_Persistence_IdentityMap)[47]
           protected 'objectMap' =>
             object(Tx_Extbase_Persistence_ObjectStorage)[48]
               ...
           protected 'uuidMap' =>
             array

As I said I didn`t change nothing in the code. Nothing added nothing 
deleted. What is going on ?

Best regards,
Dawid Pacholczyk

p.s. I`m using TYPO3 v. 4.5 beta 4
latest git version of extbase_kickstarter
