CruiseControl.net, NAnt, NUnit test output formatting

Hi All,
I'm trying to configure TypeMock to run with CruiseControl using NAnt and NUnit, and I've everything builds correctly now. However, since Typemock requires NUnit to be run as a exec task, now whenever a test fails, the Error section of the webdashboard is display differently as before.
eg. Before Typemock and running Nunit as NUnit2 task the error looks like:
Errors: (1)

Tests Failed.

After using Exec task to run Nunit the error output looks like:
Errors: (2)
C:CI_Toolsdefault.build(684,14):
External Program Failed: C:CI_ToolsNUnit 2.4.7in unit-console.exe (return code was -100)
NUnit Test(s) failed in assembly: epservices.vpo.DocManagement.Controllers.

Is there a way to format the error output like it was before? I mean there's really one error, however, the way the output is parsed makes it appear to be 2 errors. Are there any XSL template file to parse NUnit errors correctly when running in a exec task?

Thanks a lot for the help!
