title: libMobileGestalt copySystemVersionDictionaryValue: Could not lookup ReleaseType from system version dictionary
body: <p>I have been testing prior to submission of an update... from iOS4, and have run into the following... 1) creating PDFs from my app. 2) appears to be inconsistent, as I can create new PDFs without issue in most cases. 3) the crash log indicates a crash at line 341 of ExportView, which I have configured so that the only item on the line is a CFRangeMake. Note in the console that there is a value, as the same value is used in several lines.</p>
  
  <p>A few notes: using Xcode 4.6, target is iOS6, fully ARC, testing on new iPad.</p>
  
  <p>Any help with this would be greatly appreciated!!</p>
  
  <p>I've removed some of the crash log and console log to shorten this post! Apologies for it's length even now!</p>
  
  <p>Methods for the strings to be applied to the PDF creation:</p>

Later, I’ll have to compare it with real Italian pizza. I’m dead tired. Gotta get some caffeine! Got the caffeine! Yow! I should wake up in a few minutes! There are posters of Italia here and I’ve found a couple of places I’d like to see. Lago D’Orta di Piemonte, Galleria Borghese di Lazio- Roma, Pisa.
