An invalid XML character (Unicode: 0x8) error on author submit workflow

System

I have created a custom workflow from the visual workflow modeller for our authors to fill out some information and select a 'reviewer' to review and approve their submit. The workflow fails to instantiate only when one specific user is selected from the drop down list. I populate the list of reviewers in the workflow using a custom configuration file. Anyone seen this before?

Error:

Failed to instantiate a workflow model. Click details for more information, or contact your system administrator.

Is this workflow works fine without custom_instantiation?
If yes then there would be some problem with custom_instantiona.cfg, the code you have posted is not clear.

Else you have to check the roles given to the reviewer. Some times it gives error while user has not certain roles for the given task.
