kded4 crashed with SIGSEGV in QDBusPendingReplyData::setMetaTypes()

[Adric Riedel]

I just updated to Kubuntu Karmic, and this message appeared at startup (not the first one, but a subsequent one). Several other errors appeared at the same time.

I do not know which version of kde4libs (or kdelibs4) I have, but I'm up-to-date as of 2009-09-24.

It looks like the Network Management KDE Daemon crashed. Is this problem reproducible?

[Adric Riedel (adric-riedel)]

I will let you know. As far as I can tell, the Network Management APPLET is working right now... although since I upgraded to Karmic it hasn't let me actually connect to any networks it sees, so some backend thing may have been crashing every time.

[Adric Riedel (adric-riedel)]

I have been unable to reproduce this bug for the last few days; it is probably safe to assume it was some momentary upgrade glitch.
The problem with the knetworkmanagement applet connecting to other networks (that are password protected, only) is a different unrelated bug.

[Jonathan Thomas (echidnaman)]

Ok, thanks. Feel free to reopen this bug if the crash re-occurs.

[Martin Kögler (mkoegler)]

Probably caused by failing to connect to system dbus. I am able to reproduce a simliar backtrace on Debian squeeze and OpenSuSE 11.0, if I stop the system dbus.
