Re: [xmlvm-dev] Crash in XMLVM new-ios-api when app is started from another app

[JR S. <sc...@we...>]

To follow up on my own question, I resolved this.  This was tricky, 
since the debugger was of limited use as one cannot trace into native code.

The crash happens in UIApplication:didFinishLaunching with options, but 
BEFORE hitting the "Java" version of this subroutine.  It actually 
happens while trying to "wrap" the NSDictionary "launchOptions" 
argument, which explains why this only occurs when launching from Mail, 
and not from the home screen.

The crash is due to a "bug" (really, omission) in the WRAPPER_CREATOR of 
NSDictionary.  See patch below:
