Attribute preprocessing does not work when there many columns

[GoogleCodeExporter]

When automatic preprocessing is not used for csv import, and the user wants to 
preprocess fields manually by dragging the field from data field pane, there is 
the following error:"Neplatné mapování! Spusťte prosím znovu krok 
mapování..."

It may be linked to too many columns warning. In the stable "-demo" version, 
this works OK.

The csv file is attached.
