problem with couchdb does not allow ubuntuone-client to run

[Jayson Reis]

After all upgrades, I can't run ubuntuone-client-applet.
Here is what happend.
ERROR:dbus.connection:Exception in handler for D-Bus signal:
Traceback (most recent call last):
  File "/usr/lib/pymodules/python2.6/dbus/connection.py", line 214, in maybe_handle_message

  File "/usr/lib/pymodules/python2.6/couchdb/client.py", line 1035, in _request
    raise ServerError((status_code, error))
ServerError: (401, '')

And trying to run couchdb manually I receive this.
Apache CouchDB 0.10.0 (LogLevel=info) is starting.
{"init terminating in do_boot",{{badmatch,{error,shutdown}},[{couch_server_sup,start_server,1},{erl_eval,do_apply,5},{erl_eval,exprs,5},{init,start_it,1},{init,start_em,1}]}}

Crash dump was written to: erl_crash.dump
init terminating in do_boot ()
I did not know where to post so I posted it here in ubuntuone-client.

Here are some additional info received over IRC from a different user with the same problem:

<rtgz_> tchernobog, now try to start ubuntuone-client-applet from the terminal
<tchernobog> yes
<tchernobog> ouch
<rtgz_> tchernobog, if it says something, please copy-paste here
<tchernobog> i will use a pastebin
<tchernobog> so i don't spam here
<rtgz_> tchernobog, okay

<rtgz_> tchernobog, okay, the good news is that auth server is working fine so this does not seem to be _that_ server-side issue.
<tchernobog> yep, i last used the client to upload files on friday on this particular machine
<tchernobog> it went fine
<rtgz_> tchernobog, wait, this is something wrong with client-side couchdb
<rtgz_> tchernobog, open seahorse and navigate to the 'login' keyring
<tchernobog> yes
<rtgz_> tchernobog, do you see the entries "Desktop Couch user authentication" ?
<tchernobog> yes, there are two
<rtgz_> tchernobog, there may be several of them
<tchernobog> one is 'oauth' and one is 'basic'
<tchernobog> for desktopcouch
<rtgz_> tchernobog, okay, since we need a quick solution, try to remove the Desktop Couch user auth keys. They will be recreated when needed and desktopcouch will reinitialize your local installation.
<rtgz_> rtgz_, the data will not be affected since desktopcouch will rewrite the configuration for the database only.
<tchernobog> i deleted them
<tchernobog> however trying to exit the applet and re-opening it shows the same error
<rtgz_> tchernobog, then try to start the applet again. 401 means that local couch db is rejection your access as unauthorized, but this does not make sense to me at the moment since the only way to alter auth credentials is to remove them and create the invalid ones.
<tchernobog> doesn't get to that
<tchernobog> i've got ACCEPT all 127.0.0.1 in my fw rules, before anyone asks
<rtgz_> tchernobog, okay, the firewall does not seem to be an issue, since this is HTTP auth error
<rtgz_> tchernobog, okay, trying to restart the desktopcouch - /usr/lib/desktopcouch/desktopcouc...

Hi! This bug has been fixed in the latest stable point release of desktopcouch (yesterday). It is a race condition with desktopcouch startup that causes incorrect credentials to be used.

The source release that fixes this problem is https://edge.launchpad.net/desktopcouch/0.5-stable/0.5.1-stable

This is now being packaged and proposed as a stable release update for Ubuntu 9.10 (Karmic). The bug where the fix is being tracked is https://code.edge.launchpad.net/bugs/442120

Oops, the real bug is https://bugs.edge.launchpad.net/ubuntu/+source/desktopcouch/+bug/461114 .
