Hm, I can't reproduce this here with Qt 4.7 beta2 and KDE 4.4.95 (aka 4.5rc3). Could you perhaps post more accurate steps to reproduce, in case specific conditions are necessary? Attaching your yakuakerc might also be interesting.

Also, could you clarify "for a while"? Does this only occur with post-4.5-branch-off trunk?

yakuake (2.9.7+) on KDE Platform 4.5.62 (KDE 4.5.62 (KDE 4.6 >= 20100729)) using Qt 4.7.0

mmh it might well be since i switched to the qt4.7 experimental branch, but i can not say definitly.
seems it's also not easy to reproduce... i'll examine closer when exactly this is triggered and report back.

It's noteworthy that none of the backtraces contains any Yakuake code, so while it's not impossible for Yakuake to be at fault, this is more likely to be a bug in Konsole or kdelibs or Qt.

Guys, could you tell me a bit about what distributions you are all using? The initial reporter is using Gentoo; is that also the case for the rest of you? I still can't reproduce the problem, but if there's a distro-related pattern I can look into setting up an install.

I'm using Chakra Linux here, KDE 4.5.3 Kernel 2.6.36

Slackware 13.1. Qt 4.7 and KDE from trunk, everything compiled by hand :) It seems that the bug started to show up after I changed from Qt 4.6 to Qt 4.7. But it's just a guess.

Cheers,

Qt 4.7 RC1 from Debian (experimental) with self built KDE from trunk.

I've been using Qt 4.7 here for half a year or so, too, hm ..

I use openSUSE 11.3. Since the update yesterday I can not reproduce the crash. Now I have (all installed from repos):
Qt: 4.7.0
KDE Development Platform: 4.5.3 (KDE 4.5.3)
Yakuake: 2.9.7+

openSUSE 11.3 with KDE:KDE4:Factory:Desktop repository.

crash is still reproducable with latest updates:
 start yakuake -> open some tabs -> change profile -> ctrl+d all tabs -> crash. on subsequent runs, changing the profile alone will crash.

my tip would be recent changes to the way konsole / kdebase4-session handles profiles. i've always noticed slight discrepancies between the profiles menu in yakuake and konsole.

The profiles menu in Yakuake isn't actually in Yakuake, but rather opened by the Konsole KPart component, and identical to the one used by Konsole. Yakuake actually has no hand in or influence over profiles at all.

In any case, yes, this is very unlikely to be a Yakuake bug since it appeared without changes in Yakuake, and no Yakuake code appears in the backtrace. I'd investigate it anyway if I could reproduce it, which I still can't.

would confirm this to be a konsole kpart bug, since changing profiles in a kate embedded terminal also crashes.

I am using Gentoo (that's where the backtrace was generated), but today this bug also appeared on Ubuntu 10.10. Right in the first session after the reboot after updating to KDE 4.5.3 (ppa:kubuntu-ppa).

yakuake (2.9.7) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.0

- What I was doing when the application crashed: open yakuake
start top, open a new tab start iostat -k 2, open a new tab (ctrl+shift+n) issue ls -lh
close the third tab with ctrl+d
quit iostat, write exit
quit top, ctrl+d -> the last tab is rebuild/restarted
now right-click -> close this tab
crash

My previous bug 246562 happen in dolphin with console shell.
Actually tested this morning, the same actions and it haven't crash.

Seems to be more yakuake related than konsole ?

This is from my patch for bug 240037

I'll remove from trunk (1194920)  and 4.5 branch (shortly).

Sorry for the issues.

I"m still looking at this - I don't think the patch caused this.  We'll try to get it fixed for the new release.

It may be a kdelibs issue.

I have downgraded to KDE 4.5.2. The Problem is gone, so it doesn't seem Qt related.

It also happens when you press the "-" button to close the tab, specially if you are working on something important.

Maybe it solves the crashes from 246652 if they were caused by this memory corruption.

#54 Thanks for looking at this.  Yes I can still reproduce.  I think I've found a way to do it:

right click (I have left handed mouse) anywhere in session
I get a warning "Konsole::SessionController:showDisplayContextMenu: Unable to display popupmenu for session "Shell"", no GUI factory avabilabe to build popup.

Then do a ^D and it crashes.

i wondered what changed recently to cause this.

It works, but of course is less than ideal without the context menu available ;)

The fix for people who never use the context menu was committed in comment #54, right?

i've only experienced this bug for the last few days/weeks. Probably since i've updated from qt 4.6/kde 4.4 to qt 4.7/kde 4.5 (and now qt-4.7.1/kde-4.5.3, the crash is still there).
I'm not using suspend/whatever (it's a desktop) and i've never opened a menu in yakuae, so this is probably unrelated to those.

[1] http://websvn.kde.org/?view=revision&revision=1182570

Gökcen: I know about this issue, see #54. And again, I see no relation with r1182570.
And I can't see the warning that #55 mentions here, when right-clicking the terminal, in either konsole or yakuake.
So I'm still waiting for steps to reproduce the bug.

(In reply to comment #68)
> So I'm still waiting for steps to reproduce the bug.

Only in Yakauke:  Right click inside the konsole part. Press ESC. Press CTRL+D. It always crashes.

Valgrind session of crash

Gökcen: your vg log doesn't have my #54 fix, so it had a lot of noise (the lack --nofork didn't help either), and not enough debug symbols everywhere.
But thanks to #69 I could finally reproduce this bug. Valgrind says:

[...]

and now I understand what's happening. Indeed the regression comes from the patch r1145720 for bug 170806, because removeClient() on the guiFactory unplugs actions, i.e. tries to access a widget that doesn't exist anymore (TerminalDisplay).
This tells me that the destruction order is a bit strange in konsole then (when the guiFactory got autocreated in showDisplayContextMenu), but ok, I'll have a look at fixing this in kdeui to restore former behavior.
We only wanted to make the factory forget about the client, not to unplug actions one by one (which sounds slow, too).

SVN commit 1197480 by dfaure:

Tune down the fix for bug 170806 so that the factory forgets about the client, but doesn't unplug every action one by one
 (which is slow, and which can crash if one of the associated widgets was already deleted like in bug 246652)

I'm not really familiar with valgrind, sorry about that. Anyway, thanks for your help.

In Konsole there is still a bug about GUI Factory, I'm writing since it may be related to this bug. Steps to reproduce:

1- Open Konsole,
2- Open a new tab
3- Right click to open the context menu
4- Press Esc to cancel context menu and press Control+D to close active konsole tab
5- Right click to open context menu in the tab that we've just switched.

Actual results:
Context menu does not show up, and in .xsession errors there are lines like:

konsole(1532) Konsole::SessionController::showDisplayContextMenu: Unable to display popup menu for session "Shell" , no GUI factory available to build the popup.

I can't apply this since in KDE 4.5.3, I don't have workaround commit introduced in comment 61. I have commits introduced in comment 54 and comment 72 applied to KDE 4.5.3. 


When try to debug this I see that, check of factory pointer below is skipped since factory is not NULL:

    if (!factory()) 
    {
        if (!clientBuilder()) 
            setClientBuilder(new KXMLGUIBuilder(_view));
        
        KXMLGUIFactory* factory = new KXMLGUIFactory(clientBuilder(), this);
        factory->addClient(this);
    }


but popup pointer is set to NULL after this line:

    QMenu* popup = qobject_cast<QMenu*>(factory()->container("session-popup-menu",this));

After that, in else part of popup check, 

Konsole::SessionController::showDisplayContextMenu: Unable to display popup menu for session "Shell" , no GUI factory available to build the popup.

message is displayed with kWarning.

By the way, in Yakuake I can't reproduce the bug I mentioned. It's reproducable in Konsole only.

SVN commit 1198536 by dfaure:

Warn when a xmlguiclient was deleted without being removed from the xmlguifactory first.
This would crash until kdelibs-4.5.2, where it crashed in other cases (see r1197480) :)
Now it doesn't crash (hopefully), but it warns because it leaks e.g. popup-menus.

yakuake (2.9.7) on KDE Platform 4.5.3 (KDE 4.5.3) using Qt 4.7.1

- What I was doing when the application crashed:

Qt: 4.7.1
KDE Development Platform: 4.5.3 (KDE 4.5.3)
Yakuake: 2.9.7

Crashed when right clicking then closing the terminal via "exit" in shell, ctrl+d, or right clicking on tab.

The bug is still reproducible in KDE 4.6 Beta 1. If you try to change the Profile yakuake crashes. 

Yakuake 2.9.7+ 
KDE 4.5.80 (opensuse RPMs)
QT 4.7.1

I'm still experiencing this bug in kde-4.7.0, qt-4.7.3
Close a tab with ctrl-d and konsole crash. I've only experienced this crash once since I upgraded to 4.7.0 a month ago so it must be quite rare. I used to experience it every few days in older versions.

I didn't have debug symbols compiled in now but I'll get you a backtrack if it happens again.
