As I mentioned in my case, the images load fine when running through
XCode, but not as a standalone binary. So, I guess the images
themselves are fine. As producing an isolated test case scenario is
going to be prohibitively difficult in my case, all I would like is a
way to detect this happening so I can behave accordingly. Im my
application, The "-11" errors start getting coughed up after a delay.
Is there any way I can detect this error happening? My code that calls
CGImageSourceCreateFromURL doesn't appear to produce null image
sources, so I can't detect and handle this error condition.
Is there any way I can detect this error condition?

And, if there is a 10.5.5 coming out (whether or not there is, I can't say so), getting this submitted through the DTS channel today, if it's an OS-level thing, might get you the fix you need more quickly.
