Nested update panels cause a "Internal error. Invalid writer object.".  Our
application has many instances of this configuration.  When the exception

1. See attached test project.

Actual Results:
Exception occurs.

Expected Results:
page should render.

How often does this happen? 
Every time.

Additional Information:
When the project is run under Visual Studio it runs without issue.  When run
under apache with mod_mono the exception occurs.
