I have a similar problem after yesterday's Maverick update - but on login only, I can start kded4 manually fine and it works as expected.

I had the same error that Phil has and got rid of it by removing packages obex-data-server and obexd-client (this will also remove KDE bluetooth functionality).

I had the same crash, Kubuntu 64 bit, after upgrading from 10.04 to 10.10 beta. Removing all the obex related packages did the trick, many thanks to Erdewit.

This is a really problematic bug. It would prevent networkmanagement from working at all (the computer would not connect to the wireless AP). After removing the bluetooth packages everything went back to normal.

Is this a packaging issue?

I can confirm that removal of the packages obex-data-server and obexd-client stopped kded crashing for me.

Downgrading the bluedevil package from version 1.0~rc4-0ubuntu1 to 1.0~rc3-0ubuntu2 works as a workaroud for me, kded4 starts again.

KDE bug https://bugs.kde.org/show_bug.cgi?id=251359 It is fixed in master. Could you backport the fix?

Same problem and solution as Phil. And luckily, to my surprise, removing bluedevil did not stop my logitech dinovo edge (connected by bluetooth dongle) from working :) Thanks a bunch erdewit! Would have liked to try to downgrade bluedevil, but can't figure out how...

I had the same error, noticed in rekonq having cookie probs (unable to start the cookie handler service). This ment that I could not log on to Gmail or to bank service. After removing all installed obex stuff and rebooting, all but bluetooth is ok.
