When running a brand-new MonoDevelop 2.4 ASP.Net MVC application on Mono
2.10.1, using the "Mono / .Net 4.0" profile, the application output indicates
that a NullReferenceException occurs when trying to show the web application. 
OS is Fedora 14, using RHEL5 mono packages.

Reproducible: Always

Steps to Reproduce:
1. Start MonoDevelop
2. Create a new ASP.Net MVC project
3. Right-click on project name, select "Options".  Under "General", change the
profile to "Mono / .Net 4.0".
4. Press Ctrl-F5 to run the web application.

Actual Results:  
Exception is shown in Application Output as soon as a page-load is attempted. 
Application is not displayed.

Expected Results:  
Application is displayed.

Tracked this one down a little bit.  Seems to be an issue with finding the
web.config file, or any configuration file.  The line in question tries to
access cfg.Section.EncoderType, and throws a NullReferenceException because
Section returns null.
