title: Xcode 4.4 keeps crashing
body: <p>Every time I open my app in Xcode 4.4 it crashes.  It never used to do this in Lion and being very close to submission after about 6 months of work, I'm pretty annoyed to say the least!
  This is part of the crash report if it helps; I can't make head nor tail of it.  If anybody can help me, I'd be forever in your debt.</p>
