Comment (by gk):

 Okay, I finally managed to reproduce another bug I was hunting. (I still
 can't paste the log which makes the report a bit tricky, bear with me :) )

 Steps to reproduce:

 1) Use an .apk based on `28329_15`
 2) Once started click on the gear icon and enter a (working) vanilla
 bridge in the bridge details
 3) Go back to the bootstrapping view and hit the Connect button
 4) Once you see the "SUCCESS connected to Tor control port." message on
 the log, click again on the gear icon
 5) Disable the proxy, go back to the bootstrapping view and tap Connect
 6) You'll see a "Unable to start Tor" message after a bit mentioning a
 NullPointerException when invoking
 `org.torproject.android.control.TorControlConnection.setEventHandler(org.torproject.android.control.EveentHandler)`
 7) Tor stops bootstrapping as a result
