Upgrade to latest TpQt4.
You have not installed all the dependencies correctly. KDE Telepathy relies on a daemon to be running called telepathy-mission-control-5. This should be available in your package manager already. You will also probably want telepathy-gabble and telepathy-haze which provide access to jabber and libpurple(MSN, ICQ etc) respectively.
Make sure you have telepathy-auth-handler installed. Also check all the steps in the following section.
It could be one of three causes.
Have you installed the telepathy-text-ui? If not install it.
Do you compile and install your programs to a non standard directory (anywhere but /usr)? The text-ui (like other parts of Telepathy) is Dbus activated, when the dbus method is called dbus itself finds the correct application to handle it and launches it. However it cannot do this if dbus does not know about the application. You need to make sure the files in yourinstalldir/share/dbus-1/services/* is copied to /usr/share/dbus-1/services.
If you have installed it since starting a telepathy component there is a good chance that the daemon (mission-control) will have started, any channel handlers installed since then are not recognised.
Therefore, After you perform any of the above troubleshooting steps, it is necessary to restart mission-control-5( you can do this by killing the already running mission-control-5 process and then starting it from /usr/lib/telepathy/mission-control-5 or /usr/lib/mission-control-5).
You need to install a 'connection manager'. These are upstream telepathy components that talk to the various IM networks. They should be available from your distribution.
Jabber/Gmail/Facebook : Telepathy-gabble
+ Plenty more.
You need to check if your avatar (user picture) is small enough. Maximum file size allowed is 8192 bytes, maximum allowed dimensions for avatars are 96x96.
We switched the library we use for MSN, make sure you have telepathy-haze installed, delete your MSN account and add it again. If you are up to date it will now use Haze as a backend.
This is a known bug in kde and the way in which qt dbus activated application start.
in your home folder edit .config/Trolltech.conf look for section [qt] if none create one and add
you can replace oxygen with your favourite style.
