I'm on Kubuntu 9.10 and yesterday I decided to upgrade from KDE 4.3.2 to 4.4.2 - bad mistake - I am no longer able to get Kontact up and running.

I think I've got Akonadi working right as the following report shows no errors:

I can start the individual programs, but I can't start Kontact.

Trying from Konsole I get the following error:
<unknown program name>(6003)/: Communication problem with "kontact" , it probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken." "

Dos this help? http://userbase.kde.org/Akonadi_4.4/Tro ... g#Apparmor

(OT tip - if you set your distro in your forum profile it often helps in troubleshooting)

I've tried all the help on that page, but I still can't get it to load. I'm seriously considering starting again if I knew how.

This may or may not assist you.

I run sidux with KDE exclusively on all my systems, with the exception of my file server (Debian stable).

After a recent dist-upgrade I was unable to launch Kontact on my primary desktop system.

However I was able to launch each "individual" kontact component such as kmail, akregator, and kaddressbook as stand alone applications. Which in fact they are, Kontact acts as a front end so to speak.

This may be a workaround that could help you.

In my case there is one notable exception to the above mentioned workaround korganizer!!

With sidux this was put down to a bug in the current qt 4.6.2 package in Debian sid (unstable), according to reputable advice posted on sidux irc.

qt 4.6.x is to my understanding binary compatible with 4.5.x hence the KDE 4.3.4 packages currently in Debian sid ought to run without a problem.

If the workaround I mentioned doesn't work for you it may well be a distro specific problem rather than a KDE problem

Cheers.
