Hi,

I just updated to KDE 4.7.3. Now klauncher crashes after I execute the first command with the following error message:

Code:
KLauncher ist nicht über D-Bus erreichbar. Fehler beim Aufruf von start_service_by_desktop_path:Connection is closed


In English: "Klauncher is not available via D-Bus. Error executing start_service_by_desktop_path:Connection is closed"

After that, I cannot use klauncher anymore until I restart KDE. This problem always occurs after executing the first command, no matter which command I use.

In .xsession-errors I find the following entry:
Code:
kdeinit4: Shutting down running client.
klauncher: Exiting on signal 15


Also, kdm.log has a message:
Code:

klauncher(5358) kdemain: No DBUS session-bus found. Check if you have started the DBUS server.
kdeinit4: Communication error with launcher. Exiting!


DBus is up and running, even after the crash of klauncher.

I cleared /var/tmp, but the problem remains.

Do you have any ideas?

Thanks!

Hi,

Have you found a solution? I'm having the same issue with kde-4.7.4 each time I open a file dialog with the cd/dvd image manager (trying to add an ISO).

Code:
pred ~ #
pred ~ # VirtualBox &
[1] 29327
pred ~ # klauncher(29377) kdemain: No DBUS session-bus found. Check if you have started the DBUS server.
kdeinit4: Communication error with launcher. Exiting!

Same problem here. It seems that Qt get confused when I run VBox as root in a user's kde session.
I have solved my problem running VirtualBox as a user following this tutorial http://en.gentoo-wiki.com/wiki/VirtualBox.
It is needed to relogin the user in kde to run VirtualBox properly.
Let me know if this also solve your issue.
