Since nobody else is saying anything, I'll just give my thoughts, which are as follows: WTF?!? You're instantiating an object of this class when calling some random method, like a method of the SOAP-exposed API? No, that's not good at all.

BTW, if you're looking for a role model distribution on how to do your classes, SOAP::Lite is not it at all. Wondered why its development ground to a halt, I don't think it's coincidental.
