Kopete crashes when connecting to jabber server

[zdenek.zikan]

This happens even if I delete kopete's configuration files and add a new account to kopete. After i go online (automatically after startup or manually) Kopete crashes with following stacktrace. It seems that the stacktrace is incomplete (#6 0x00000003 in ?? ()) but I don't know what debugging package to install, so if anybody helps me, I'll provide more complete stacktrace (it crashes every time, so reproducing is not a problem).

Program: Kopete (kopete), signal SIGSEGV

[Jonathan Thomas (echidnaman)]

I'm setting this bug to private since the stacktrace contains your jabber ID and password.

[Jonathan Thomas (echidnaman)]

Nevermind, it's just the pointer to the address holding your password. Better safe than sorry though.

[zdenek.zikan (zdenek-zikan)]

Maybe it is the same bug as https://bugs.launchpad.net/ubuntu/+source/qca2/+bug/350882 but I'm not sure. Could somebody check it out?

[Jonathan Thomas (echidnaman)]

It looks like it's crashing in the same function, but I don't know if we have enough info to determine if it's the exact same crash.
Regardless, it does appear to be a qca bug.

[zdenek.zikan (zdenek-zikan)]

Can somebody tell me how to get debugging packages for qca2? I couldn't find any in Jaunty repositories, so I'm wondering if there are any.

[Jonathan Thomas (echidnaman)]

You might try the dbgsym packages. The following wiki page outlines how to get dbgsym packages for most of the software in Ubuntu:
https://wiki.kubuntu.org/DebuggingProgramCrash#Hardy%20Heron%208.04,%20Intrepid%20Ibex%208.10,%20and%20Jaunty%20Jackalope%209.04
(See the first section)

[zdenek.zikan (zdenek-zikan)]

Jonathan> Didn't help. QCA2 debugging packages don't seem to be there.

[zdenek.zikan (zdenek-zikan)]

I'm not sure how much is this information useful, but problem remains after upgrade to KDE 4.2.3 and Qt 4.5.1.

As for QCA2, I can see theat in upstream, there is already version 2.0.2, while in Ubuntu, there is 2.0.0 for very long time (since Hardy). Would you consider updating Jaunty's version of QCA2?

[zdenek.zikan (zdenek-zikan)]

The problem remains after upgrading to KDE 4.3 beta 1 on Jaunty. What about switching QCA2 to newer version. Is there any reason for still using the old (probably buggy version)? Or do you think that changes between 2.0.0 and 2.0.2 are not related to this bug?

[Rohan Garg (rohangarg)]

Hi
Can you still reproduce this crash with the latest version of Kubuntu i.e Lucid Lynx?
