- Info:
* TBB/Linux version: tor-browser-gnu-linux-i686-2.2.34-3-dev-en-US.tar.gz
* TBB/Linux version security status: verified gpg sig as good
* TBB/Linux obtained from: Official Tor homepage
* Desktop flavor: Gnome / Version: 2.32.1 / Distributor: Ubuntu / Build Date: 04/14/2011
* Linux version: Ubuntu 11.10 / oneiric
* Kernel version: 3.0.0-14-generic #23-Ubuntu SMP Mon Nov 21 20:34:47 UTC 2011
* Methods of executions tried: Terminal and double clicking from within Nautilus
* Method of extraction/run environment: extracted tar.gz to home directory of a limited user,
ran within the folder: tor-browser_en-US

While Vidalia/Tor both launch and run, I receive this error when running start-tor-browser from within a Terminal or double clicking from within Nautilus:

==> Qt: Session management error: None of the authentication protocols specified are supported <==

I'm not alone. Here is a sampling of others encountering this bug with no clearly
defined resolution. For some, their Tor does not function when they receive this
error, while mine does. I wonder what accounts for the difference in experiences
with this bug.

Am I missing certain Qt libs? Is this a PATH error? Is it Aurora causing this
error? What does this message indicate and how does it, if at all, effect my
Vidalia/Tor session(s)? I cannot spot any visible malfunction but this error persists with each launch.

In addition, when TBB/Linux is launched, another user appears. When I execute the
command, "w", it shows another user in numerical output but not in name
or any other details. All commands to identify and pin down this mysterious guest
fail to identify the source. Granted, I'm running Ubuntu 11.10, which in my opinion
is [one of the] the most buggiest versions I've ever played with.

One post on a mailing list (possibly referenced above in one of the links) contained
a dev request to run Tor with debug, which the user did, but the bug remains.

Thank you for TBB/Linux, let's find the cause of this bug and correct it.
