Hi Fabian.

This is a known bug - if I remember correctly it was already fixed in  
trunk (I'm too lazy to look it up in forge right now ;) ).

This happens as the result object of a query is kind of "lazy loaded"  
since the TYPO3 4.5 release. This allows the pagination widget to modify  
the query before fetching the results for example. So before you actually  
request an object from the query result object, it does not hold any  
domain models.

The bug here is, that calling the count() method on the object will just  
look how many objects have already been instanciated, but it does not  
actually fetch the objects from the database.

Without testing: $products->getFirst() should do the job. But be aware  
that you won't be able to use the pagination viewHelper like mentioned  
above after doing this.
