There was a period where we were using static initializers to map the mime type
to the contents parser and this would not always work (platform dependent). When
that initializer methods failed, the result would be no mapping and therefore an
unexpected default type for the parsed contents, and therefore a null after the
dynamic_cast, and finally, nashing and wailing.

The current (head) version will show the same symptoms only if you are not
including SdpContents.hxx. This approach allows you to substitute your own
parsers and determine what types you want to manage.

Let me know if you are including SdpContents.hxx and are still having the issue.
