Deck creates thousands of preview requests #724
Description
Steps to reproduce
Just click the Deck app!
Expected behaviour
Deck to work without generating all these preview requests
Actual behaviour
When I use the Deck app I noticed my server load shot up. Looking in the browser console I see thousands of calls to /core/preview.png?file=... - there seems to be a never ending stream of them.
My appdata_XXX/preview directory is now up to about 30% of the total storage I am using(!)
This does not happen for any other app.
