imageobject in task leads to strange result in pdf

Hello,

I'm trying to utilize the <task> element. But if I add imageobjects the pdf result looks broken. 

The example document I use is listed below and the rendering result is attached.

Any advice what I'm doing wrong? The input document validates in Eclipse. 

Best regards, Lars
