Comment 1 Raphael Kubo da Costa 2009-05-26 05:12:47 UTC 
Can you confirm if this is still valid for a recent trunk? If so, what file were you trying to play? Does it always happen only to this file?
Comment 2 Juan Carlos Cornejo 2009-05-28 04:34:48 UTC 
Hi,

I am also experiencing crashes as soon as dragon player starts up. This is even before I attempt to have it play any file. The crash output is similar to the one Alexander reports.


I am using the SVN trunk, the latest revision I compiled is 973644. I have always experienced this crash.

Thanks,
Juan Carlos
Comment 3 Raphael Kubo da Costa 2009-05-28 04:42:45 UTC 
By "always" do you mean you've never been able to run Dragon?
Comment 4 Juan Carlos Cornejo 2009-05-28 05:35:57 UTC 
Right, I have never been able to run this version of Dragon without crashing.

I can still successfully run the one from KDE 4.2.3, but not one after KDE 4.3.0 beta 1 and on.

Thanks for looking into this.
Comment 5 Alexander Opitz 2009-06-11 22:11:22 UTC 
It still happens to me, I removed the config file but nothing changed.

To note; Running the dragonplayer from kubuntu karmic (4.2.90) works.

Comment 7 Dario Andres 2009-06-12 00:14:46 UTC 
Reporter from bug 196098 is experiencing this on 4.2.91
Adding Phonon maintainer.
Comment 8 Aaron Nixon 2009-06-24 01:00:03 UTC 
Just FYI line 170 is pINTERFACE_CALL(setAspectRatio(aspectRatio));

0xb7f0e64c in Phonon::VideoWidgetPrivate::setupBackendObject (this=0x90b2d70) at /root/kdesvn/svn/source/kdesupport/phonon/phonon/videowidget.cpp:170

aspectRatio is Phonon::VideoWidget::AspectRatioAuto
Comment 9 cedric 2009-08-13 11:11:37 UTC 
I get the same crash since some days ago (I compile kde and phonon from svn trunk)
the crash occur in every application that uses a Phonon::VideoWidget : dragon player, the video plugin in Amarok and digikam so far.
Comment 10 cedric 2009-08-16 18:15:55 UTC 
the crash occur because phonon from my local build loads phonon_xine.so from my system installation from /usr/lib/qt4/plugins/phonon_backend/ instead of /opt/kde4/lib/kde4/plugins/phonon_backend/
renaming /usr/lib/qt4/plugins/phonon_backend/ fixes the crash.

the problem is in KdePlatformPlugin::createBackend()
Comment 11 Dario Andres 2009-08-16 18:17:26 UTC 
@cedric: indeed you had a conflicting Phonon from Qt and KDE.
Comment 12 Martin Sandsmark 2009-11-29 03:41:16 UTC 
Does it still crash?

And make sure that you don't have conflicting Phonons installed.
Comment 13 Alexander Opitz 2014-01-08 10:41:12 UTC 
This issue is very old and I don't have crashs at the moment, so closing this issue as invalid.
