Package: vidalia
Version: 0.2.10-3
Severity: normal
Tags: patch

Hi,

vidalia.config script contains wrong logic I think: it kills the
system-wide Tor daemon if vidalia/tor-daemon-interaction is set to
"nothing" or "one-off". According to the debconf templates, "nothing"
means:

   * No configuration:
     leave Tor running for now. Vidalia will not be able to
     communicate with Tor until it is manually reconfigured - see
     "/usr/share/doc/vidalia/README.Debian" for more details;

In that case, I don't think Vidalia's config script should interfere
in any way with the system-wide Tor daemon.

On the other hand, when this debconf parameter has the "permanent"
value, I think Vidalia's config script should stop it as documented:

   * Permanent takeover:
     stop Tor and simply let Vidalia handle starting it whenever you
     run Vidalia (not usable on a multi-user system).

The attached Git patch (against current packaging repository master
branch) fixes this, I think.

I'm only setting severity "normal", but this bug may deserve a higher
severity as it interferes with (and even kills) another package's bits
while asked not to do so.
