[TYPO3-commerce] PHP Fatal error: Cannot use string offset as an array in [...]class.tx_commerce_belib.php on line 870

[Carsten Sann]

Hi List,

when I try to create new products or even change a category I get this 
message in the Apache error log. I searched the newsgroup but did not 
find anything. Can anyone help?

Typo3        4.1.5 (4.1.2 doesn't work either)
ext_commerce 0.9.2
Apache       2.2.6
PHP          5.2.5

Regards
Carsten
