[Evolution-hackers] Problems with camel

[Jeffrey Stedfast]

generally, a big hint is when a camel_<type>_new() function doesn't
exist, it means you have to subclass it.

also, the reason it crashed is because you can't cast an object to a
class. (well, you can, but you won't get a valid class pointer)
