 I tried reproducing this on an Android 6.0 emulator, emulating both x86
 and armv7 architectures. The app didn't crash when clicking on the
 settings cog during either test. It sounds like the crash is occurring
 during the transition between the bootstrapping screen (using the
 BrowserApp as the Activity) to the first preferences screen (using the
 TorPreferences Activity).

 There aren't too many places where this can crash within the app code
 (verses within system code), however we are making some assumption about
 variables and return values being non-null in the TorPreferences code.
 Maybe some of those assumptions are wrong, and the code should correctly
 handle these. I'll fix these potential issues, at least.
