NSURLConnection crashing under 10.5.7

Question

I have a little app that downloads stock prices and was working perfectly (for years) until my recent upgrade to 10.5.7. After the upgrade, the program would crash on this

Answer 1

For what it's worth, this seems to be fixed on 10.5.8 --- but it's been replaced by a new bug which prepends the redirect's response-body to the real response about 2% of the time. (Easy to reproduce by spinning on -stringWithContentsOfURL:, but we've also seen it in the wild.) Reported that bug as radar #7169953.
