Description

When calling `navigator.app.backHistory()` on android 4.1 I see the following on the logcat output:

W/webview_proxy(16553): java.lang.Throwable: Warning: A WebView method was called on thread 'Thread-8550'. All WebView methods must be called on the UI thread. Future versions of WebView may
not support use on other threads.

Although this exception is thrown cordova does return one position in history.

The exception is not thrown on an HTC Bravo with android 2.3.7.
