Description Marcus Harrison 2009-06-13 12:39:13 UTC 
Version:           2.0 (using 4.2.4 (KDE 4.2.4), Gentoo)
Compiler:          i686-pc-linux-gnu-gcc
OS:                Linux (i686) release 2.6.29-gentoo-r3

Dragon crashed when trying to stream this video:
http://stream.qtv.apple.com/events/jun/0906paowdnv/m_0906jhoiudvfvn_hd_ref.mov

Having downloaded the video and tried playing it again, it just refuses to play it, without crashing.
I've compiled everything with USE="quicktime" and have made sure libquicktime is installed.


The backtrace:
Application: Dragon Player (dragon), signal SIGSEGV

Comment 52 Dima Ryazanov 2009-11-30 02:37:53 UTC 
I decided to look through xinestream.cpp. I see many instances of "if (m_stream) {...}", and a few places that set m_stream to 0. However, there's no check for m_stream being 0 in XineStream::playbackFinished. Should there be one? Can anyone guarantee that m_stream will not be 0 there?

Comment 60 Jonathan Thomas 2009-12-16 06:28:46 UTC 
We got a backtrace at https://launchpad.net/bugs/359966 that seems to indicate that xine_close is indeed trying to close a null stream. I would assume that this would mean that we could not ensure that m_stream always be around when playbackFinished() is called. In the case of the first backtrace, it looks like there's a point in time where when the code enters into the: if (!xine_open(m_stream, m_mrl.constData())) statement and unlocks the mutex right before calling playbackFinished which gives an albeit small window of opportunity for a separate thread to do something that deletes m_stream before the mutex is locked again in playbackFinished.

It probably wouldn't hurt to check for m_stream's existence before deleting anyways; better safe than sorry.

SVN commit 1062986 by jmthomas:

Check for the Xine stream's existence before closing it. In the sense that the stream shouldn't really be closed between the mutex close/open event() and playbackFinished() this bug is still present. It should not cause crashes now, however.

If it is the same bug...

got those crashes (about 4 of them) in a row in 10mins period of time, while doing different things (being away, browsing menus etc)

the status NEW means confirmed, else it would read UNCONFIRMED :)
Comment 117 Alejandro Nova 2010-08-22 04:38:55 UTC 
What steps will reproduce the problem?
1. Reproduce a stream.
2. Have any hiccup, that drops you out from the server.
3. Boom!

What is the expected output? What do you see instead?
Bangarang should fail gracefully.

This is the backtrace.

Comment 123 Myriam Schweingruber 2011-06-07 23:28:26 UTC 
Please use another backend, the xine backend is deprecated as the upstream development is stalled. 

You can choose between the gstreamer backend or the vlc backend, both are actively developed and maintained.
