attempt to insert nil object from objects

[Viktoriia]

I've got crash on start stream for iOS only and get this issue:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSPlaceholderDictionary initWithObjects:forKeys:count:]: attempt to insert nil object from objects[14]'
*** First throw call stack:

I'm using latest iOS sdk 2.6.73, but it seems flashphoner problem
