CXF is not handling SOAP fault

Using the cxf-codegen-plugin (version 2.7.3), I have generated client
ports/proxies for a SOAP service. When the SOAP service returns a successful
response everything works fine. However, when the SOAP service returns a
fault, it seems that CXF is not able to convert the SOAP fault in the
correct auto-generated exception. Here is the stack trace for such an even:

I'm wondering if I am missing a property or interceptor that is causing CXF
to choke when trying to convert the SOAP fault into a Java exception.

Please help.
