QTPro - Failure after installing new language

[Prinsessenjurk]

Hi, after a sucessfull install of QTPro 4.2 in my shop I installed a new language (german)

now it shows while selecting a new product (only in German, Dutch works well):

 

Warning: Invalid argument supplied for foreach() in /home/voolstra/domains/prinsessenjurk.nl/public_html/catalog/includes/classes/pad_base.php on line 388

 

You can see at http://www.prinsessenjurk.nl by selecting german langue and select a product.(life site!)

 

Row 388 = foreach ($attributes[$oidindex]['ovals'] as $attrib) {

 

But it does not ring any bell for me.

 

Can someone help me ?; thanks in advance.
