The main problem was that the file does not exist. Maybe we can something do with the Exceptions - that they were not shown.

Deleting a file that does not exist @ DropBox - shows the stack trace in logging. I think that problem have we analysed - and found no real solution. Using FileNotFoundException (sub if IOException) - but the handling has some problems?
