[AC-2955] iPhone Ti Mobile SDK 1.6.2 Crash after hiding ImageView

This problem occurs when the app has been busy for some time (1 out of 5 times). Seems to be a null reference error. However my ImageView is created on app start and is never set to null or removed from its parent view. The problem seems to be fixed (though it's only a workaround) when I return if newValue is null in method DoProxyDelegateChangedValuesWithProxy. Relevant crash report entries: ...

    Christopher In order for us to progress this issue, please edit your ticket to include a proper [Use-case](http://wiki.appcelerator.org/display/guides/Contributing+to+Titanium#ContributingtoTitanium-CreatingGoodUsecases). Do you think this issue is the same as TIMOB-4493. If so, your usecase will be crucial, as the other users are not able to reproduce the problem. Also, would you format the console output block using the wiki syntax provided? Thank you
