Subject: kscd does not play any CD

Date: Wed, 28 Nov 2012 22:25:27 +0100

Package: kscd
Version: 4:4.8.4-2
Severity: grave
Justification: renders package unusable

Dear Maintainer,

whatever CD I try to play with kscd player, it does not play
anything. Since vlc can play all track, audex can rip them, I think it
is a problem with kscd. kscd can still read out the track list. Since
I am not aware that I have any special setup, there is a fair chance
that the bug affects everybody and makes the package completely
unusable. If that is not the case, please downgrade the bug.

Please let me know, if I can provide additional information.

Thanks,
Rainer

I can reproduce this: when just clicking on the play button in kscd, it
immediately segfaults.

After setting the environment variable KDE_DEBUG=1 and ulimit -c
unlimited, I get a core dump:

Hopefully that helps to further debug this problem.

FYI: I’m using the latest pulseaudio packages
(mentioning it because libpulse shows up in the
backtrace, though maybe unrelated):

Well, this seems a different issue ("does nothing" vs "click and 
crashes") than the reported one...

Unfortunately it not not useful, since kscd is a "unique instance" 
application which forks right after the start, so the trace of the 
parent process is not useful.
However, you can get a better one (and try to debug kscd) just by 
running kscd as
$ kscd --nofork
also, installing kdemultimedia-dbg will help providing a more useful 
stack trace.

Also, you could please paste the output of
$ dpkg -l | grep phonon
?

Thanks,

Possibly, but the reporter was not very specific. Chances are that this
might be the same issue, or at least related.

Thanks for those hints. Here is the new backtrace:

Thanks, much better.

Looking upstream, I found https://bugs.kde.org/show_bug.cgi?id=265597 
which now leads me to the question: do you both have udisks installed?
If not, does installing it and rerunning kscd changes the situation?

Thanks,

I have udisks 1.0.4-6 installed.

I think we are in fact dealing with two separate issues here:

1. The segfault I reported happens when there is no optical drive
   recognized on the system. My ThinkPad X200 does not have an optical
   drive, but there is one in the docking station. Unfortunately, it
   only works correctly when the notebook is booted with the docking
   station attached.

   That is, when submitting the backtrace, I had not booted the notebook
   in the docking station, so that the optical drive was not
   detected. Simplifying this, I suppose the same crash will happen when
   you disconnect the OD in your computer on purpose, or rmmod the
   driver.

   This issue can be put into a separate bugreport. Should I file a
   separate issue or do you want to open it?

2. After rebooting my notebook in the docking station and inserting an
   audio CD into the optical drive, kscd does not crash anymore when I
   press the play button.

   However, neither does it actually play the CD. In the terminal in
   which I started it, I get:

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
Setting new source 
New source:  QUrl( "" )  
Transitioning to state "playing" 
State change 
Moving from "null" 0 to "ready" 1 
1 
Transitioning to state "null" 

   And that’s it. The application itself shows the title of the first
   track scrolling by but remains at 00:00 and does not play anything,
   even after many minutes. I attached a screenshot.

   Using mplayer cdda://0 -cdrom-device /dev/sr0 works fine.

   I noticed that /dev/cdrom was not present on my system, so I used
   ln -s /dev/sr0 /dev/cdrom and that made kscd work. Its output in the
   terminal is now:

QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.

I will just clone this bug, so backlog etc is preserved.
Let's continue that issue on the new bug.

Interesting; possibly it won't change much, but what if (without the 
symlink you just created) you install phonon-backend-vlc, make it the 
default in `kcmshell4 phonon` and try again?

Also, you might want to enable the two debug areas for kscd in 
`kdebugdialog`, and rerun kscd.

This is not release critical. When you don’t have an optical drive, you
cannot use kscd at all.
