[maemo-developers] Telepathy Mission Control - Account keeps disconnecting from custom connection in harmattan

[From: Sudheer K.]

Hi Daniil,

Thanks for your response.I have been debugging my ConnectionManager and
Connection code for a while with no success.

This is the sequence of events that happen when I execute the DBus Command
manually(or when mission control automatically attempts to connect to my
connection manager):

dbus-send --type=method_call --print-reply
--dest=org.freedesktop.Telepathy.AccountManager
/org/freedesktop/Telepathy/Account/vicar/tel/vicar0 org.
freedesktop.Telepathy.Account.Reconnect

1) The telepathy client (mission control in this case) calls
ConnectionManager::RequestConnection() method.
2) My connection manager creates a connection object, registers the object
on D-Bus, Emits NewConnection signal
3) Mission control calls Connection::HoldHandles()
4) Mission control calls Connection::Connect()
5) My connection changes the status to Connected and emits StatusChanged
signal.
6) Mission control emits AccountPropertyChanged signal with connection
object path set to "/org/freedesktop/Telepathy/Connection/vicar/tel/vicar"
and ConnectionStatus set to 0 (Connected).
7) Immediately after this I see in the dbus-monitor output that mission
control emits AccountPropertyChanged sign with connection object path set
to "/" and ConnectionStatus set to 2 (Disconnected).

After step 6, the Connection object status remains as Connected (set in my
code) but client-side account status changes to Disconnected [1].
Apparently, something is happening between steps 6 and 7 that causes
mission control (client) to disconnect from the Connection. From the debug
messages I added to each of my methods I can confirm that none of my
methods are called between 6 and 7. And as I said earlier, step 7 does not
happen in Fremantle with the same code. You can look at my
ConnectionManager [2] and Connection [3] code.

I requested "Cellular" privilege in my aegis manifesto. Running accli -I
<pid> command shows my application binary has same privileges as
"telepathy-ring" and "mission-control-5".

I wanted to install the debug package for mission control to get more
details but the package is not "yet" available for harmattan PR1.1. Is
there anything else I can do to debug this issue?
