Comment 1 Kevin Funk 2010-02-19 10:08:33 UTC
How old is your checkout? Just did some changes to it yesterday evening.
Comment 2 Adrian Cozma 2010-02-19 10:14:27 UTC
I've just upgraded the packages from openSUSE's KDE4.4 repos about a couple of hours ago, and this is the first attempt to launch Amarok since then.
Comment 3 Myriam Schweingruber 2010-02-19 11:04:56 UTC
This looks related to Qt 4.6.2, we just have to check with Plasma first.
Comment 4 Adrian Cozma 2010-02-19 11:20:08 UTC
Don't know if it helps, but downgrading Amarok to v2.2.2 (built for KDE4.3.1, not for 4.4.00) helped circumvent the issue.

Well, no, this is certainly not the way to go, since you don't use a Qt 4.6.2 build anymore in that case. And it is a bad workaround, since you have to downgrade to a previous version. That is never a good solution, and can sometimes cause quite some issues.
Comment 6 thomas coopman 2010-02-19 14:57:12 UTC
It looks like it's the info applet that causes this problem.  If you remove info from the plugins in amarok_homerc, amarok should start again (removing amarok_homerc works also (back-up first)).

If you then start amarok and add the info applet again and restart, amarok crashes again.
Comment 7 Benedikt Bauer 2010-02-20 22:35:11 UTC
I've got the same thing over here: amarok crashes after displaying the splash screen. I couldn't find any info aplet in the amarok_homerc so I tried removing it completely. This didn't improve anything. Amarok still crashes.

Here's the backtrace:

Comment 8 Myriam Schweingruber 2010-02-20 22:54:43 UTC
Benedikt, sorry, but your backtrace lacks debugging symbols. Please see here on how to produce a valid backtrace:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Also you didn't specify which distribution you are using. After talking on IRC with various people affected by this bug it turns out to be OpenSuSE specific.

Sven, any news on this?
Comment 9 Benedikt Bauer 2010-02-21 18:02:39 UTC
Second try and sorry for the inconvenience:

Myriam, you're right, mit distro is openSUSE 11.1.

The command
amarok --version 
gives the following:
=====
Qt: 4.5.3
KDE: 4.3.5 (KDE 4.3.5) "release 3"
Amarok: 2.0.1

I hope this will give you more and better information!
Comment 10 Myriam Schweingruber 2010-02-21 18:41:21 UTC
Benedikt, sorry, but what you have is something completely different. Also you are using a very old and obsolete Amarok version, the current stable version in OpenSuSE is Amarok 2.2.2, please upgrade. 
You should not be affected by this bug here, since it only happens with the 2.3 beta version and for people who use KDE SC 4.4.

Comment 13 Adrian Cozma 2010-02-26 20:11:26 UTC
The new Amarok build 2.2.90-57.4 (previously 2.2.90-3.1), as it appeared today in openSUSE's KDE4.4 repos, crashes at the same point in Qt libs. I can provide the backtrace if necessary.

Myriam, I don't know how QT deals with backwards compatibility, or what different calls makes Amarok in 4.4 compared to 4.3. That's why I though there is a possibility knowing what version worked may help someone. Thanks for the tip - I already am aware mixing stuff is bad. But it's a lot worse hearing only the pressed keys sounds.
Comment 14 Myriam Schweingruber 2010-02-27 03:26:23 UTC
Adrian, this looks more and more like a problem with the OpenSuSE packages, since those are the only ones with this particular problem. It doesn't happen on any other distribution. I strongly suggest you check with OpenSuSE.
Closing this to DOWNSTREAM.
Comment 15 Adrian Cozma 2010-02-27 03:59:32 UTC
Myriam, thanks.

For the who may be interested, it appears to be a problem of package versions and repositories. Basically, one should change its packages to Packman's, despite having earlier versions/builds.

This is Qt bug 6932, not an openSUSE issue.  The forum reports also concern a crash on startup, but an unrelated one caused by mismatched packages.

See http://bugreports.qt.nokia.com/browse/QTBUG-6932 and the backtrace at the end of this comment.

Will, thank you for the feedback. Seems this is Qt 4.6.2 specific, then, since the other distributions ship Qt 4.6.1 as default with KDE SC 4.4, and I haven't seen a single report from another distribution for this bug so far.

Amarok crashes at startup on Kubuntu lucid

New crash information added by DrKonqi

This bug seems still to be present with Qt-4.6.2 on Gentoo Linux, KDE 4.4.1... Any information on which package should cause the segfault if not Qt, KDE oder Amarok itself? I don't think there is much left.

Here's the console output of Amarok until the crash:

QObject::connect: Cannot connect (null)::updated() to Dynamic::DynamicPlaylist::invalidate()
Calling appendChild() on a null node does nothing.
QObject::connect: Cannot connect (null)::tracksReady( Meta::TrackList ) to Playlist::DynamicTrackNavigator::receiveTracks( Meta::TrackList )

Maybe it's due to the "invalid index 1"?

Comment 42 mtz.inc .. 2010-03-16 20:31:53 UTC
i have a feeling this bug is going to be reported a lot. This is a critical and a very prominent bug and amarok should own the crushes and do something about them.

Why not disabling the info applet or building amarok in a way that crushing applets dont bring it down?

how are amarok applets handled? how easily can then crash amarok?
Comment 43 Myriam Schweingruber 2010-03-16 20:55:27 UTC
And how do you expect us to do that? For users with an already set Info Applet this is hardly possible. This report doesn't affect new users since the Info Applet is not a default setting, unless they activate it.
Also, the cause of the bug is not the Info Applet, so why should we disable it?

Comment 45 Dario Andres 2010-03-17 13:10:05 UTC
Workaround: 

Try removing the info applet (by editing or erasing the amarok_homerc file located in $HOME/.kde/share/config/)
The exact .kde folder name depends on your distribution, it can also be ".kde4"

Trying to start Amarok. Crashes everytime.
Comment 55 Mark Kretschmann 2010-03-20 07:23:00 UTC
Alexis Menard (Qt developer) thinks that this is not actually a Qt bug, but rather a bug in Plasma.

I'm really not sure about this, but I'm reassigning this to Plasma so that you guys can have a look, and judge.

Thanks :)

It is sufficient to remove the "info" widget from amarok_homerc - then it works. At least this did the trick for me.

Would have been nice if developers included a check which disabled this plugin on startup and showed a warning to the user that this plugin may cause crashes due to yet unknown reasons and that one needs to reenable it manually.

I had previously had errors about phonon, resulting in the sound failing. So i rebooted, and found that I can't get amarok to open at all.
The only thing I changed in amarok was setting up some of the applets to show pictures and video etc.

When I looked at my copy of amarok_homerc, there was no entry for the info
widget, and deleting the whole file made no difference.

Interestingly, removing amarok using Kpackagekit, rebooting and then reinstalling does not fix the problem. Even on the 1st occasion that I tried to run amarok after the reinstall I got the same error.

Daaaaaaaaaaave, you just removed all CCs, be careful... and re-add them!

Comment 73 Lydia Pintscher 2010-03-22 12:00:48 UTC
actually adding back everyone that was removed...
Comment 74 André Fettouhi 2010-03-22 12:07:11 UTC
Is this fixed now? Is it fixed in the next version of Qt or Amarok or Plasma?
Comment 75 Sven Krohlas 2010-03-22 12:13:40 UTC
A workaround will be in Amarok 2.3.1 or can already be found in git master.
Comment 76 Myriam Schweingruber 2010-03-22 13:53:20 UTC
I was never subscribed to this bug ... please don't add me to any bugs, I get those in the inbox already.
Comment 77 Alexis MENARD 2010-03-23 05:55:34 UTC
A fix will be in Qt 4.6.3 so please remove the workaround as soon as it is released. I have also open a bug for another crash that happens due to the workaround in Plasma (same workaround that was the origin of this crash) :

QVariant WebView::itemChange(GraphicsItemChange change, const QVariant &value)
{
   if (change == QGraphicsItem::ItemSceneHasChanged) {
       //FIXME: QWebPage _requires_ a QWidget view to not crash in
places such as
       // WebCore::PopupMenu::show() due to
hostWindow()->platformPageClient() == NULL
       // because QWebPage::d->client is NULL
       d->webView->page()->setView(viewFor(this));
   }
   return QGraphicsWidget::itemChange(change, value);
}
For the report :
https://bugs.webkit.org/show_bug.cgi?id=36436

At the end if the very first bug was reported (the one Plasma was trying to workaround) and therefore fixed the next Qt version then we could have removed the workaround and Amarok would never had any issue.

Alexis, 

The work around does not change anything that it did not make sense to change in any case, so it should be completely safe, even when the root cause of the bug is fixed.

Comment 88 Nuclear Peon 2010-05-06 03:37:36 UTC
This was occuring exactly as described with me. Same issue, same crash output.

I have a Gentoo system with latest genkernel (2.6.32-r7 I think), QT 4.6.2, and KDE 4.4.2 (masked by ~x86).

Amarok would crash on both 2.2.2 and 2.3.0 versions. Upgrading to unstable amarok 2.3.0.90 seems to have resolved the issue and amarok no longer crashes upon startup. I did remove my ~/.kde4/share/apps/amarok/* contents beforehand though it may have had no effect.
