I see this error
Unable to read symbols for /Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.2 (8H7)/Symbols/Developer/usr/lib/libXcodeDebuggerSupport.dylib (fi
Since you're using a different SDK than the solution you pointed at, you do need to tweak the commands to make it right. It should fix itself if you do
cd "/Developer/Platforms/iPhoneOS.platform/DeviceSupport/4.3.2 (8H7)/Symbols/"
sudo ln -s ../../Latest/Symbols/Developer
(enter your password at prompt)
Might not help your actual crash, but it should get rid of the file not found message.
