the very first time i used QWeakPointer i gave a small groan about this. by 
the end of the day (was converting all the Plasma related code over to this 
and some other Qt 4.6 features) I was singing a very different tune. it really 
does help, doesn't add to the verbosity of the code in practice (store and 
check the value of data() in a local var) and makes it very easy to spot 
problem code.
