This is a problem with the Facebook Kopete plugin. It was an experimental plugin being considered for includsion for Kubuntu 9.10. Unfortunately, it was seen as too unstable for default inclusion and has been removed from the default lineup. You may wish to remove the "kopete-facebook" package so that Kopete will not crash because of it.

[Shura (shura01)]

Ok, thank you !

[Joshua Dunamis (dunamis)]

Thanks, now I know the problem is kopete-facebook. I'll keep it hoping a fix as soon as.

Here is a little extra information in the stack trace (I installed the kdenetwork-dbg package):

do you still have this crash with the kopete-facebook package from karmic-proposed (kopete-facebook 0.1.4-0ubuntu1.1) ?

[Joshua Dunamis (dunamis)]

No, with this upgrade I don't have this crash anymore. I seems fixed. Thank you!!!

[Joshua Dunamis (dunamis)]

Today the bug is here again. It shows itself after a message board "You are disconnected" from Facebook account and now it appears every time as before the upgrade.

[Steve King (steveoldmanse-launchpad)]

I am running with kopete-facebook 0.1.4-0ubuntu1.1 and the problem is still there.

[Steve King (steveoldmanse-launchpad)]

I don't know whether this helps, but it looks to me that I get the crash when I quit Kopete after it has previously reported it has lost its connection to Facebook. It will always lose the Facebook connection if I run Kopete for long enough (e.g. 60 minutes or so), but if I quit Kopete before it loses the FB connection then there is no crash.

[Lorenzo Bettini (bettini)]

I'm experiencing the same crash and the backtrace shows the same problem in ~PasswordedAccount (I'm using kwallet to store password).

[Harald Sitter (apachelogger)]

Facebook now supports chat via XMPP (aka Jabber), which is a native plugin to Kopete. Due to this change of circumstances kopete-facebook was recently removed from the archives in favor of the present solution. It is currently not planed to deploy further updates to the version used in Kubuntu karmic.
