TypeError when attempting to download a Comma-delimted Text of a report

[peterson_eric_d@…]

Clicking on Comma-delimited Text to save a report, I get no data but the header row in MS Excel. Looking at the log I see the following error. It is a rather long query, below. It works fine to see the data on the screen, yet my users would like to play in MS Excel (go figure).
