Comment:

 I see the same error.  I am running Ubuntu 11.10, Vidalia 0.2.16-git, Qt
 4.7.4, and Tor v0.2.2.35 (git-b04388f9e7546a9f).

 I am a new developer working with Vidalia, Tor, and Qt.  It seems Vidalia
 sends the SETCONF command and then MAPADDR with an expiration timestamp of
 NEVER.  Tor returns OK.  Based on the control protocol spec it seems
 there's not an option to clear the setting only to reset to a default
 value.  At a minimum we could set an expired timestamp.

 An explanation on the apply highlight and apply all radio buttons would be
 helpful.  Since Tor returns the path for the configuration file, wouldn't
 an easier and more simplistic approach be to stop tor, rewrite the
 configuration file, and then restart tor?

 I'm willing to implement the fix once a solution is proposed by a Tor
 developer.

 Thanks,
 Randall
