IOS 8 UIWebView file upload failed

I have an iOS app that uses some cordova plugins and uses the standard UIWebView wrapper.

On iOS 8, I load an image into a UIWebView, the app crashes. Xcode gives "application terminated due to memory error" and not much more. This issue also occurred in Safari, but Apple fixed this in iOS 8.0.1.

I found this solution a few weeks ago , which has a bug fixed. Now, however, iOS 8.1 is down and the problem reoccurs. I've tried all sorts of combinations of deployment targets and basic SDK settings in the CordovaLib.xcodeproj settings and my main project build settings, but I wasn't very lucky.

I am testing this on an iPhone 6.
