Well, the *pseudo-code* looks to be correct, assuming that dynamic_cast<> is 
returning null for objects that are not APE::File*. Is there anywhere else in 
the actual code where apeFile is being assigned?

Of course, you can try it anyways and reset all static members when you go 
into your function and see if that fixes it. If so there's probably something 
else going on within the rest of the code.
