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?
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
By "always" do you mean you've never been able to run Dragon?
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.
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.
*** Bug 196098 has been marked as a duplicate of this bug. ***
Reporter from bug 196098 is experiencing this on 4.2.91 Adding Phonon maintainer.
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
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.
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()
@cedric: indeed you had a conflicting Phonon from Qt and KDE.
Does it still crash? And make sure that you don't have conflicting Phonons installed.
This issue is very old and I don't have crashs at the moment, so closing this issue as invalid.
