libMobileGestalt copySystemVersionDictionaryValue: Could not lookup ReleaseType from system version dictionary
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.
A few notes: using Xcode 4.6, target is iOS6, fully ARC, testing on new iPad.
Any help with this would be greatly appreciated!!
I've removed some of the crash log and console log to shorten this post! Apologies for it's length even now!

Answer
It turns out that the libModileGestalt had nothing do with the crashing. Found out via a tip on Apple forums that the CGColor was probably nil. After isolating and installing log statements before the actual call, that it was indeed the case. In fact, all of the colors... text, title and date were coming over as NULL. So, I've got the crashing to stop by installing a test and apply statement in the create PDF method. Now... to find out why the colors are not being passed over!
