In the backtrace there is a recursive call between relayouting in the item 
view and the rating overlay. I will see to fix that.

What is also bugging me is this:

No itemShortInfo could be retrieved from the database for image
"PICT3091.MRW"

Which should not happen, why can the picture not be retrieved by its Url? Do 
these files exist?
But that comes second after the first problem.
