Comment 1 Dario Andres 2010-01-03 15:09:48 UTC 
This is probably related to bug 220152 / bug 202982.
It is a bug in the Phonon KDE multimedia subsytem, when using the Xine multimedia library.
Thanks

Comment 3 Dario Andres 2010-01-03 15:21:46 UTC 
I could reproduce the crash using the provided URL here using:

Qt: 4.6.0 (kde-qt master commit 747ff8e6ef6f5a1163dfa75bc9ac4755ce7083d1
        Date:   Tue Dec 15 11:58:13 2009 +0100)
KDE Development Platform: 4.3.86 (KDE 4.3.86 (KDE 4.4 >= 20091231))
kdelibs svn rev. 1069096 / kdebase svn rev. 1069104
phonon(kde-support) svn rev. 1069080
xine-lib 1.1.17
on ArchLinux i686 - Kernel 2.6.31.6

Steps to reproduce:
--

- Launch DragonPlayer to show http://wwitv.com/tv_stream/b2750.asx ("dragon http://wwitv.com/tv_stream/b2750.asx" from Konsole should be enough)
- Wait some time and Dragon will crash.. Here it crashes after 1 minute.

I debugged the crash and, in fact, "stream" was 0 on "Phonon::Xine::XineStream::event"

A weird thing is that I got a XIOError, while the original backtrace was normal on thread 1...

The backtraces are identical, why keeping open both reports?
