[TYPO3-shop] SQL Error with alternative product category language

[Oliver Wand]

Hi,

when trying to enter a Product Category (Alternative Language) I receive 
the following error in the backend:

2: SQL error: 'Unknown column 'subtitle' in 'field list'' 
(tt_products_cat_language:NEW443f54a039f41)

Any hints?

Cheers,

Oliver
