title: Xcode 3.2.1 crashes on startup on OS X 10.6.2
body: <p>I have uninstalled it via the devtools uninstall command and reinstalled 3 times to no avail.  This all started when I downloaded <code>iphone_sdk_3.1.3_with_xcode_3.2.1__snow_leopard__10m2003a.dmg</code> from the DEV portal and installed.</p>
  
  <p>I've trashed my com.apple.xcode.plist file, uninstalled all xcode plugins as well as Growlcode and I still can't solve this.</p>
  
  <p>Here is the error information:</p>
