this normally happens just after the player tries to play a file whose name has an encoding error (although file names, or filesystems actually, don't quite have associated encodings) and I force the player to play the next song. in this situation the MediaObject's queue should be empty. I also have this log [comments between brackets]:

Comment 19 Harald Sitter 2012-06-18 02:46:29 UTC
Mhhh..
So I was just looking at bug 302018 and it is said there that the crash happens after amarok failed to go to the next track and consequently stopped playback which lead to the reporter triggering a manual play.

2 things
a) is it a general pattern that amarok first stops?
b) someone please get a full debug log by running this in a terminal:

export PHONON_DEBUG=5
export PHONON_BACKEND_DEBUG=5
export PHONON_GST_DEBUG=5
amarok --nofork --debug &> amarok.log

that creates a file amarok.log, please compress that one and attach it to this bug

TIA


also for developer reference: I do not think that the fix from comment 2 has any value as m_pipeline is reffed in the ctor and only unreffed in the dtor, so I do not think the pipeline goes away while we work on it

  as I said previously, I don't use amarok, but yes, the pattern is like that.

Harald: I was just browsing a few upstream reports in gstreamer with various keywords I use when searching for duplicates and came across this report: https://bugzilla.gnome.org/show_bug.cgi?id=678220 It was fixed a few days ago only, might be related.
Comment 23 Harald Sitter 2012-06-25 10:50:47 UTC
Not sure, the upstream report is about a deadlock whereas this bug is about a crash. This might still be an upstream problem, as I mentioned from our POV this should not crash there as we hold a reference to the pipeline for the entire life time of our wrapping class.

Marcos please not the "that creates a file amarok.log, please compress that one and attach it to this bug" part of my request. Also I do not see any amarok output, are you sure you stated it with --debug?

I'm not using amarok, but an application I developed myself in pyqt/pykde. I can try to see if I can reproduce the bug in amarok, but I'm not sure it will pick up the files that trigger this crash (in my case, filenames that include bytes that don't decode in my global encoding; in my case, UTF-8).
Comment 25 vin_c_007 2012-07-02 18:07:34 UTC
(Sorry for the delay)
I got some full debug logs, and I have found that the bug is linked to a file that does not exist anymore. The song appears greyed out in the playlist.When amarok tries to play it, it stops, freezes then crashes.

I first thought of an encoding problem (amarok3.log), but it also happens when the whole path does not contain any special characters. (amarok4.log)

I can now reproduce the bug anytime.

I do very much think that this is in fact an issue with GStreamer itself. There at least is a similar crash I know about when some element's state is not properly reset on source change. Which would very much put this issue into the realm of gstreamer's playbin2. To know for sure it would be good if someone who is affected to get his hands on a gstreamer git master build and see if the issue also presents with that. (you'll need at least libgstreamer and -base)

It still doesn't work with amarok 2.6 and Phonon-backend-gstreamer Version:4:4.7.0really4.6.0-0ubuntu1 (is it the right one ?)

Not sure if it will help, but after an update to opensuse 12.2, i was having a crash similar to 300742, which is marked as a duplicate of this.

All notifications would crash in phonon-gstreamer.  Eventually, i found out that gstreamer couldnt see any plugins, even though they were installed.  I deleted my gstreamer registry in ~/.gstreamer-10, and it then worked fine.

Comment 54 Harald Sitter 2012-11-10 16:27:58 UTC
Having more affected users now, let's again try to find the root cause by getting more samples. Before you start please try to get a hold of phonon gstreamer 4.6.2 (your distribution may probably have packages available somewhere, best ask in a forum or in your distribution's respective IRC channels).

Please open a terminal and do the following:

export PHONON_DEBUG=5
export PHONON_BACKEND_DEBUG=5
export PHONON_GST_DEBUG=5
amarok --nofork --debug &> amarok.log

This starts Amarok so yo can try to trigger the crash. Once that happens you may get a new backtrace via the debug dialog, simply save that to  a file in your home directory. The commands above also create a file called amarok.log in that directory.
Next run the following in a terminal:

export PHONON_DEBUG=5
export PHONON_BACKEND_DEBUG=5
export PHONON_GST_DEBUG=5
export PHONON_GST_GST_DEBUG=5
export PHONON_SUBSYSTEM_DEBUG=5
amarok --nofork --debug &> amarok-v.log

Again this starts Amarok so you can trigger the crash. This time you do not need to get a backtrace as it will be the same as in the previous attempt (if you want to you can still do at the off chance of it being different that would certainly help us). This time we created a file called amarok-v.log in your home directory.

Finally if you feel that your computer is fast enough please do the following (or continue reading at +++++++++++++++++):

Run the command kdebugdialog (either via a terminal or Alt+F2 or your application menu) in this dialog select all and make sure that debug output is in enabled. This activates debugging for every piece of KDE software and can be undone once you are done by simply running kdebugdialog again disabling all debug output.
Once you are done with that we again turn to a terminal:

export PHONON_DEBUG=5
export PHONON_BACKEND_DEBUG=5
export PHONON_GST_DEBUG=5
export PHONON_GST_GST_DEBUG=5
export PHONON_SUBSYSTEM_DEBUG=8
amarok --nofork --debug &> amarok-vv.log

Same procedure as before. This time it creates a file called amarok-vv.log which will contain insane amounts of debug logs (we are talking thousands of lines per second here). Don't forget to run kdebugdialog if you don't want continuous excessive debug output from KDE software ;)

+++++++++++++++++
Now you only need to compress the files and upload them to this bug. This is easiest done in a terminal by doing:

cd $HOME
xz -9 amarok.log
xz -9 amarok-v.log
xz -9 amarok-vv.log

(note that the last command will fail if you have not done the last bit for somewhat more powerful computers). You should now have 2-3 files in your home directory named amarok.log.xz, amarok-v.log.xz and (possibly) amarok-vv.log.xz

At the bottom of this bug report you find a list of attachements and at the bottom of the list is a link titled 'Add an attachment' click it and start uploading the 2-3 files, please use the following as description:
amarok.log.xz -> Amarok Debug Log
amarok-v.log.xz -> Amarok Verbose Debug Log
amarok-vv.log.xz -> Amarok Verbose Verbose Debug Log

If you created a backtrace please also upload that with a useful description ('phonon gstreamer 4.6.2 backtrace' would be a good one ;)). The backtrace needs no compression as it will be a rather small file, if you still wish to compress it that is fine by us.

Please do not pack the logs into one archive though (tar, rar, zip, whatever), the point of this exercise is to get a number of samples that we can easily compare with one another so the easier we can select random samples of one type the better.

For me, it doesn't just crash between tracks without any user interaction.
Amarok first stops playback (although the desktop icon thinks it is still playing).
The crash only happens after I try to play or skip to the next track after it has entered this state.

Sometimes I get this behavior, too. And sometimes it immediately crashes on start up. Amarok 2.x is generally much more unstable than 1.x (who knows if it's actually Phonon, that's what I see - and dragon player doesn't seem to be that unstable, so there is at least something special to Amarok about this).
Comment 58 Harald Sitter 2012-11-10 18:33:57 UTC
the full debug logs attachment suggests that something in the communication between amarok and phonon gstreamer goes wrong putting latter in an undefined state so it subsequently falls on its face.

this is confirmed by comment #44, while a completely different bug to begin with it shows the same symptom so this crash here may be caused by a set of preconditions that are possibly unrelated making it a bit tricky to debug, hence why a lot more debug logs would be helpful.

Comment 71 Rohan Garg 2013-02-19 17:41:40 UTC
Hi
Would it be possible to check with the latest 4.6.3 bugfix release if this is fixed?
Comment 72 Rohan Garg 2013-02-19 17:53:32 UTC
Oh and if the crash is still there, could you attach all the logs as well ( Same instructions as in the comments earlier )
Comment 73 Myriam Schweingruber 2013-02-19 18:43:58 UTC
Setting status correctly.
Comment 74 David Roth 2013-02-19 21:29:31 UTC
Still happens, Arch x86-64 phonon-gstreamer 4.6.3 and pulse 3.0 here. It happens pretty randomly, though some tracks may be more affected than others and are more likely cause a crash, but I can't really  make out a pattern. Attachments of the three debug outputs should be coming in soonish, don't have a backtrace though sorry

> Amarok Debug Log

I do not think that is the same crash. Backtrace would be very helpful really.

The crash happens in the setupsource callback, however it appears your track started playing just fine and you got a crash *after* the callback was run...
Comment 77 David Roth 2013-02-21 17:36:07 UTC
Seems you're right, it indeed is mostly crashing after it already started playing, Done some searching and it seems like a recurrence of https://bugs.kde.org/show_bug.cgi?id=279813 with qtwebkit 2.3 Beta. Off to whine to the qtwebkit-devs and disable the Wikipedia applet in the meantime sorry for the noise.

Crash log

Amarok 2.7.0

Gstreamer 0.10.36-1

Comment 84 Stephan Diestelhorst 2013-03-20 13:43:37 UTC
Is it still worth digging through this?  If this is reported upstream, please link to the appropriate report.  Also it seems that upstream GStreamer has decided to abandon 0.10, and KDE seems to favour phonon-vlc, right?  That had some issues, hence I switched back to phonon-gstreamer.

Comment 103 Marcos Dione 2013-09-10 20:18:05 UTC
I have a small working demo of this bug, so you can paw at it more easily. I'll attach a pyqt script that depends on python, python-qt4 and python-dbus. this script receives a list of files to reproduce back to back. it also has a dbus interface so you can play with it. the way to reproduce is the following:

* provide 4 files to reproduce. files number 1, 3 and 4 have must have filenames valid in your local encoding (normally utf8). file number 2 must have a broken filename. like this:

/usr/bin/python2.7 phonon.py \
  /home/mdione/media/music/Van\ Halen/3/01-Neworld.ogg \ 
  /home/mdione/media/music/new/House\ MD\ Soundtrack/Du�rmete,\ Mi\ Ni�o\ -\ Christine\ Avila.mp3 \
  /home/mdione/media/music/Van\ Halen/3/02-Without\ you.ogg \
  /home/mdione/media/music/Van\ Halen/3/03-One\ I\ want.ogg

* let the first file finish.
* when file number 2 is not reproduced, use the dbus interface to advance and play:

qdbus org.kde.phonon_test /main next
qdbus org.kde.phonon_test /main play

* file number 3 is not reproduced, so next and play again
* BAM!

here's the output of such a run nuder gdb (backtrace attached):

Notice how file number 2's filename is actually encoded in latin1, not in utf8. I hope this helps advancing with this bug.

On the other hand, I will try to compile and try 868a0b71bc9fd79c3d00c66e830627a5f5dfd38c as requested, but I can't guarantee that that will happen. :(

Perhaps even more interesting is that it is also not correctly decoded on bugzilla. I guess that was supposed to be "Duérmete,\ Mi\ Niño\ -\ Christine\ Avila"? In which case I would ask you to actually check your system encoding because those two characters most certainly shouldn't go bad when posting something to bugzilla :S

Note: LANG needs to be a valid !C in order for the python example to reliably fail.

PHONON-GST END__: static void Phonon::Gstreamer::Pipeline::cb_setupSource(GstElement *, GParamSpec *, gpointer) [Took: 0s] 
PHONON-GST 1 
PHONON-GST BEGIN: void Phonon::Gstreamer::MediaObject::setError(const QString &, Phonon::ErrorType) 
PHONON-GST   "Resource not found." 
PHONON-GST   isFatal true 
PHONON-GST   1 

So, Phonon goes into fatal error state, python program ignores that, keeps feeding stuff, Phonon explodes (somewhat within parameters I'd say). Arguably crashing is not the nicest of things, so perhaps in the long run MediaObject should either learn to autorecover from fatal errors or refuse to do anything after having run into a fatal error.

Of course this does not explain in the least bit why Amarok would crash this way too. Amarok completely reinitalizes all phonon objects upon error, so this particular call chain of getting-bad-source-and-keep-hammering-after-fatal-error ought to be impossible in case of Amarok.

All we know is that g_object_get(that->m_pipeline, "source", &phononSrc, NULL); causes the crash. Why it does that we do not know. Crashing in that function to begin with is fun though. Crashing through a failed assert G_IS_OBJECT() is even more fun as that suggets "source" is not a gobject, and the best thing about it all is that we do not even manually set "source" but as I understand it playbin2 itself creates/inits/sets "source" based on the uri we set...

Gigantic mess, no end in sight.

I tested it in F20.
It happened once, but I don't know how to reproduce it.

amarok (2.8.0) on KDE Platform 4.11.3 using Qt 4.8.4

- What I was doing when the application crashed:

Playing a song after having Amarok paused overnight.

Comment 133 Myriam Schweingruber 2014-08-10 09:26:03 UTC
Could you please all test with the phonon-backend-gstreamer 4.7.2 and make sure you use the gstreamer 1.x libraries and plugins?
If this is still reproducible, please provide a current backtrace.
Comment 134 Christoph Feck 2014-08-10 09:59:59 UTC
Myriam, are you sure phonon-backend-gstreamer has already been ported to gstreamer 1.x?
Comment 135 Myriam Schweingruber 2014-08-10 10:19:56 UTC
(In reply to Christoph Feck from comment #134)

Definitely, it is in a development branch, and it is patched in the latest Kubuntu release.
