[sldev] [HELP] passing aLLMediaObserver::onMediaMetaInfoChangeeventfrom llmediaimplwhatsoever to llviewermedia does just nothing

[Kent Quirk (Q Linden)]

I was pretty sure it was a problem with pointers-to-members and  
subclasses, but I stared at it for a while and couldn't convince  
myself it was wrong.

Just to make sure that's not the case, you might stick a log message  
in the default implementation of the change event in the base class.  
If that fires instead of the subclass event, the problem is that you  
have a reference to the wrong class when you're dereferencing the  
pointer-to-member.
