Summary:
Using `kSecAttrApplicationTag` in the query dictionary of SecItemCopyMatching() results in an "unrecognized selector" error.

Steps to Reproduce:
1. Open attached project
2. Make sure TODO: line in WRACrypto.m is not commented out
3. Run project
4. View log output for "-[NSConcreteData _fastCharacterContents]: unrecognized selector sent to instance"

Expected Results:
List of SecKey attributes

Actual Results:
"-[NSConcreteData _fastCharacterContents]: unrecognized selector sent to instance ..."

Regression:
I have only tested this on a 10.7 system, as I am using APIs that require it. But this issue has occurred on every 10.7 system I've tested it on.

Notes:
I am using XCode Version 4.2, Build 4D5163b
