Sometimes xcode does not make your crash report readable (for some reason), if so you can do the following steps:

• Find the approriate archive that created this error. You can do this by going to the organizer and right clicking on the archive and do a “show in finder”.
• Open the archive (show package contents) and copy the app (in Products/Applications) and the dSym (in dSyms) to a temporary folder.
• Open a terminal and go to the temporary folder.
• Open “/Developer/Platforms/iPhoneOS.platform/Developer/usr/libexec/gdb/gdb-arm-apple-darwin $(APPNAME).app/$(APPNAME)”
• This will give all sorts of warnings about frameworks, ignore them.
• Do: set print asm-demangle on
• And: set print symbol-filename on
• Then: p/a {address in the crash log file}

This should give you the class and the functions that is in the stack.
