Privacy Browser crashes if a dialog is displayed while the app is in the background
This is caused because a the fragment manager cannot display a dialog after onSaveInstanceState().
This bug can be triggered by loading a webpage like www.libreoffice.org that has a delayed download and then switching to a different app before the download starts. It has also been reported that this can happen with SSL certificate errors.
I am a little puzzled as to why this is happening, as the WebViews are paused when onSaveInstanceState() is called.
