I've seen that before too.  In PHP there are different options for  
how handled/displayed.  In general WordPress tries to have PHP not  
show warnings/errors for exactly these sorts of reasons.  There is  
nothing stopping an admin from enabling PHP warnings/errors from  
being shown in the return data, which is what you are probably seeing.

You should never see this for WordPress.com blogs because we  
specifically turn that off.
