AttributeError: aq_parent on images in Data table (on ZMS content root object)

Dear all,


working with ZMS2 2.13.4.1651 (Build #134c) i get the following error page / log output when clicking on "edit" on a table row of a data table defined on / extending the ZMS (content) object. 

The table uses strings, integers and an image object in each row. Other (non-image/blob) data fields could be accessed as usual / expected by my code.

The same happens when i try to access the image blob by URI within a table row of a data table by my code.

It seems the getHref (URI) could not be rendered properly.

Is this a ZMS problem or something related to Python 2.6 (what i did not assume here)? 

Is this solved in a newer build/version of ZMS?
