But the documentation says that I'd have complete access to all local

"[self isKindOfClass:[QTMovie class]]" is not a "local variable".
It's a method call (two, in fact). I find method and function calls
iffy (at best) when used in conditional breakpoints.
GDB needs to have type info to keep you from crashing during
expression evaluation of functions/methods. So you need to do
something more like the following.
(BOOL)[$r3 isKindOfClass:(Class)[NSString class]]
On ppc self will most likely be found at $r3. You can always test
your expression in the debugger console.
In a small program you might be ok with making a subclass so you can
stop in -retain or -release. But in a larger program you might have
to change too much of your code so I would temporarily use a category.
