Description

I'm starting to receive crash reports about users using an iPad 3 using iOS 9.2. When I look into the crash reports I'm seeing the following in " CDVInAppBrowser.m"

• (void)viewDidUnload
  {
  [self.webView loadHTMLString:nil baseURL:nil];
  [CDVUserAgentUtil releaseLock:&_userAgentLockToken];
  [super viewDidUnload];
  }

XCode is saying that "loadHTMLString" "Null passed to a callee that requires a non-null argument."

And in the iOS documentation https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIWebView_Class/#//apple_ref/occ/instm/UIWebView/loadHTMLString:baseURL:

I'm not sure why this only occurs for one specific user on iPad 3 and I can't seem to reproduce the problem in the simulator.

Question 1: How to fix?
Question 2: According to the user the crash happens immidiately when starting my cordova app before a button is pressed to open the inAppBrowser. When does viewDidUnload get called? I have no experience with objective C. I'm making a wild guess this is garbage collection for iOS.
