Impossible to connect to a msn account

Thanks for your bug report. Which version of telepathy-butterfly do you have installed?

telepathy-butterfly 0.1.0-0ubuntu2

Can you try running
     telepathy-butterfly --persist
in the terminal, add an account to cohoba, try to connect and see if you get meaningful output in the terminal and paste it here? (If not, you might want to try to run
   /usr/lib/cohoba/cohoba-applet
in the terminal, add it to the panel and then repeat the steps and paste the output here.

I also cannot manage to connect to msn adding a network that is "MSN messenger (butterfly)" but I also see a network that is "MSN messenger (msn)". This one also doesn't work, but If I launch telepathy-butterfly manually, the new "MSN messenger (msn)" account connects using the telepathy-butterfly I'm running

/usr/share/dbus-1/services/org.freedesktop.Telepathy.ConnectionManager.butterfly.service
launches /usr/telepathy-butterfly instead of /usr/bin/telepathy-butterfly changing this fixes the problem

Changing the dbus file did solve the problem, and the cohoba-applet became very very slow.
I don't have any output when I create or change anything with an msn account, with or without the modification of the dbus file. I had output with google talk account, but now I can't connect this :(
I'll try to reinstall all the packages to see if I can have more output.

Nothing. The only output I have it's this with the cohoba applet :

With a corrected /usr/share/dbus-1/services/org.freedesktop.Telepathy.ConnectionManager.butterfly.service file I also note the same behaviour as Julien.
I ran dbus-monitor and saw that:

-------------
signal sender=org.freedesktop.DBus -> dest=(null destination) path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
   string "org.freedesktop.Telepathy.ConnectionManager.msn"
   string ":1.55"
   string ""
signal sender=org.freedesktop.DBus -> dest=(null destination) path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
   string ":1.55"
   string ":1.55"
   string ""

-------------
and then , about 1 second later:
-------------
signal sender=org.freedesktop.DBus -> dest=(null destination) path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
   string ":1.56"
   string ""
   string ":1.56"

signal sender=org.freedesktop.DBus -> dest=(null destination) path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
   string "org.freedesktop.Telepathy.ConnectionManager.msn"
   string ""
   string ":1.56"
method call sender=:1.56 -> dest=org.freedesktop.DBus path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=RequestName
   string "org.freedesktop.Telepathy.ConnectionManager.msn"
   uint32 0

There seem to be some stuff calling still the ConnectionManager butterfly instead of msn

Need to find where

Can you check the files you have in ~/.telepathy please ? Maybe you used the previous development versions before ?

In my first comment I had a ~/.telepathy/msn.manager
Then I reinstalled everything and removed that manager so now I the add account dialog, I only have butterfly for MSN-Messenger.
The dbus-monitor stuff is ran without ~/.telepathy/msn.manager

There is a new upstream release that fixes the problem.

 telepathy-butterfly (0.1.1-0ubuntu1) edgy; urgency=low
 .
   * New upstream release
   * Fixes bug "Impossible to connect to a msn account" (Malone: #63196)

Working without reinstall. Great ! Thanks :)
