Make sure you have the .dSYM file that was produced when building your app.
Take a look at the Apple Developer TechNote "Understanding and Analyzing iPhone OS Application Crash Reports" located at: http://developer.apple.com/library/ios/#technotes/tn2008/tn2151.html
I usually look at the crash reports exception description to see why the app crashed and in what thread the crash happened - thread 0 in this case.
Check the top of the call stack of thread 0 to see what method was last called...
ImageLoaderMachOClassic::findClosestSymbol(void const*, void const**)
then really really check the parameters passed to the method. Either by inspecting your source code or perhaps adding assertions. Often I find that I passed a bogus pointer to the last method called.
