CSV output with no Text Qualifier throws error

First off, we are on BI 4.1 SP01 Patch 2.  I want to schedule a Web Intelligence report with the output format set to CSV with no text qualifier (neither single or double quotes).  In this thread Simone Caneparo suggests this is possible...

Schedule Webi report to CSV - text qualifier

Here is a screenshot of my Output Format options...

So I am able to specify nothing as the text qualifier.  However, when I run the report I get this error...

[IllegalArgumentException] <false> (Error: RWI 00011)

Am I doing something wrong?  Has anyone else gotten this to work?

Thanks,

Noel
