are you using kdelibs from HEAD with kopete from HEAD? or are you using kdelibs
from KDE 3.3.x?

> are you using kdelibs from HEAD with kopete from HEAD?

yes (I usually compile in a fresh directory, no old libs mess).

> are you using kdelibs from KDE 3.3.x?

no

Though, this was seen with KDE 3.3.0 and 3.3.1 (RELEASE TAG) as well.

I just got this crash when exiting Kopete:

I can confirm _a_ crash on logout, not sure if it's this one or not

I currently see this:

Trying to quit Kopete with accounts connected -> the readyForUnload signal never gets emitted (not sure by which plugin yet), and the shutdown timer comes in and brute-force unloads the plugins. There appear to be destruction-order problems causing various crashes with brute-force unloading. I've seen, at least, Jabber and IRC cause problems.

So, our last-resort fallback is getting called, and is causing crashes. I've never felt happy about the plugin manager's unload timer... maybe this is a sign that it should go away?

Removing the timeout, kopete hangs on shutdown waiting for plugins to say they're ready to unload (never seems to happen here). Sending a dcop kopete MainApplication quit causes Kopete to segfault.

Ideally, I'd like to make sure plugins do emit readyToUnload (or whatever it's called), and remove the plugin manager's timeout. But the real world isn't ideal, so the timeout should probably stay. A KUniqueApp crashing is better than it hanging with no visible UI ;(

*** Bug 91993 has been marked as a duplicate of this bug. ***

*** Bug 97969 has been marked as a duplicate of this bug. ***

I've fixed today several crashes when closing kopete
I hope it's fixed.

I still get crashes on exit with 3.4 RC1.

I experience the issue too (kde 3.4 rc1), using jabber and icq. I've filed a
bugreport http://bugs.kde.org/show_bug.cgi?id=100528 , but seems that my report
should be marked as a duplicate for this bug.

Not fixed.

Suggested patch

CAUSE
Richard's analysis above was correct, that plugins were not being unloaded. 
This was because KApplication::quitKopete() was never called in
KopeteWindow::closeEvent() - the logic there was broken and I can't understand
why it was left like that.


REMEDY
This patch goes quite a long way:
* Remove ref/deref complexity from the PluginManager and give responsibility
for closing down the app to KopeteApplication::quitKopete() which calls
KApplication::quit().
* Remove the WDestructiveClose on KopeteWindow - it makes it easier to use
QCloseEvent::accept() to hide the window, and the instance is deleted in any
case by ~KopeteApplication().
* Simplify KopeteWindow::closeEvent() so that it accepts the QCloseEvent in
either case, but detects when the app should also be quit, quits it using
KopeteWindow::slotQuit(), and therefore KopeteApplication::quitKopete().
* Remove redundant call to KMainWindow::queryExit() which is { return true; }
* Remove a couple of other bits of cruft.

Please test.  Many others have worked in this area before and there seem to be
a number of pitfalls - quitting the app too early (relative to the loaded
plugins - the cause of the above crash, cf #75805), quitting the app too late
or not at all (a kopete instance with no gui, cf #71657), doing the wrong thing
when the system tray icon is not used, not working with session management.  

As it's my first touch of the ball I've definitely made a glaring mistake
somewhere so help me find it!

sorry the patch doesn't help. it still crashes on logout.

Please tell me which protocols you are using and which you were online with at
the time of the crash.  Then try the following:

Start kopete
go online
switch to a text console or start another X session
in the other console/session:
ps -ef | grep kopete
gdb -p <PID of kopete>
'c'ontinue kopete when gdb has started

switch back to X
log out of KDE
switch to the other console
get a backtrace from gdb with 'bt'

protocols are icq,irc and jabber.
attachment of backtrace will be uploaded now, but we have no debug symbols so i don't think it will help you much.

backtrace of kopete crash, but without debugging symbols

Tobias: The backtrace is very useful.

Please backup your .kde/share/config/kopeterc, remove your IRC account and see if the crash goes away without it.

ok will do that after lunch :)
in 30 minutes or so.

For future reference: please paste the backtraces, instead of attaching them.

ok sorry didn't know that, thanks for correcting this.
you are right removed irc and now no crash happens anymore, add irc again and the crash comes back.

There's at least one problem case with my patch, when quitting a group chat a
warning dialog appears, causing this:

Crash when quitting KDE session, Kopete IRC + Jabber, chatwindow open with tabs
for #kopete and #kde-devel - quitting group chat warning dialog appeared.

Session management called commitData on our mainwindows, sending a QCloseEvent
to each one, and closing the group chat window showed a dialog, which put us
back in the event loop, where there was a deleteLater waiting to delete the
account?

Created an attachment (id=10055) [details]
suggested patch, respecting chatwindows' abort session shutdown needs

This patch borrows a bit of code from Kmail so that when the system tray icon
is not shown, all kopete windows are responsible for keeping the app running,
like Kmail.  

There is still a problem that on session quit, the plugin manager does not
fully complete its shutdown - the plugins are all shut down, but the
KopeteApplication destructor is called before the plugins are deleteLater()'d. 

I'm not sure if the refcount is dropping to 0 (debug output from
KApplication::debug() seems to rule this out) or the session manager is killing
the app - if anyone has debug techniques to check this please tell me.

this patch seems to work, i had no crash on shutting down kopete anymore

The patch works for me also.

CVS commit by wstephens: 

Backport fix for crashing on session exit - unload plugins properly.

What kde version should have the bug fixed? I can still experience it in kde
3.4, Kopete crashes if I logout when msn and icq are still connected.
Everything works fine if I logout having disconncted everything first. 

>What kde version should have the bug fixed?

The bug is still in kde-3.4.0. Gentoo devs have included the patch posted here in the kopete-.3.4.0-r1 ebuild, so bug your distro vendor (or, if you compiled the sources yourself, patch the sources manually). The problem will be definately gone in kde 3.4.1 (unless something really weird happens).

This patch breaks kopete as described in the gentoo bug 91423
(http://bugs.gentoo.org/show_bug.cgi?id=91423)  Also discussed as KDE bug
101008 (http://bugs.kde.org/show_bug.cgi?id=101008)

The Bug is the Bug 105442
