After reboot kontact can't be started

[hyper_ch]

Binary package hint: kdepim

I installed yesterday Kubuntu Karmic and it works fine.

However after a reboot I can't start Kontact anymore. I keep getting this
output when issued "kontact &" from the terminal:

<unknown program name>(4370)/: Communication problem with "kontact" , it
probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not
receive a reply (timeout by message bus)" "

However I can run Kmail, Akregator, Korganizer just fine as stand-alone. Also, when I delete the configs and keep adding one after the other again (like first akregator then kmail and kaddressbook and finally korganizer it works again.

Can you get a backtrace please?

[hyper_ch (bugs-launchpad-net-roleplayer)]

Well, I would supply you with a backtrace if I could figure out how to get one.

I tried to "gdb kontact" --> "run"

And then back at the gdb command prompt I run "bt" but only "No stack." was returned.

Although when I run Kontact from the KMenu I don't get to a point where the KDE Crash Application tool (I keep forgetting its name) appears.

[hyper_ch (bugs-launchpad-net-roleplayer)]

I have now achieved a backtrace and I cut the output of backtrace full after the first several hundred lines. It was in a loop and just continued to print out the same lines time and again. For me it doesn't tell anything but I hope it'll be usefull for others.

[hyper_ch (bugs-launchpad-net-roleplayer)]

Ok, I was told in the #kontact channel on freenode that this backtrace above is useless and that I should first install the kdepim-dbg package.

I have done so now and have here the new output.

[hyper_ch (bugs-launchpad-net-roleplayer)]

I downgraded now to the official ubuntu packages and kontact works just fine there.

The crash was caused by a incompatible Qt version.
