Hi Laurent,
I couldn't find a crash report in Console, but Xcode gave the following with
build and debug.
#0 0x7fff815020da in objc_exception_throw
#1 0x7fff81af26f0 in _qfqp2_performParsing
#2 0x7fff81af05b9 in +[NSPredicate predicateWithFormat:arguments:]
#3 0x7fff81af057c in +[NSPredicate predicateWithFormat:]
#4 0x7fff81af020d in _qfqp_InitializedGlobalData
Is this of any use or do you require more info.
