Lead Report Export Error

When I go to the Lead report and click on Export i get the following error:

Traceback (innermost last):

The Lead Details report in the Standard Reports works and exports fine, but the regular Report in the Lead doctype will not export due to that error (just clicking on Report from the Lead list and then clicking on Export from there).

Works for me alright. Can you share your version what columns are you trying to export?
