New crash information added by DrKonqi

amarok (2.7.0) on KDE Platform 4.10.00 using Qt 4.8.4

- What I was doing when the application crashed:

Start amarok, click Amarok in the Toolbar menu, then "Play Media...". Crash!

Sorry that I don't have solid debug symbols installed. Will do that now and try again...

- Custom settings of the application:

Using vlc backend. 
Just installed and configured appmenu-qt yesterday.

Got the following messages in .xsesssion errors, although they don't show in the command line when running `amarok --debug`:

@Alex: did you read the report before adding your backtrace? It also lacks the debugging symbols for solid, please install those and provide a better backtrace.

Reassigning to Solid.

Hi Myriam.

Yes, I did see your previous request to install Solid debug symbols, hence the apology.
I rebuilt a Debug version of kdelibs yesterday and have just reproduced the error with it. Unfortunately, the stack trace still stops at branch point #5. Any idea what other symbols I might be missing? New backtrace attached.

Cheers,
Alex

Backtrace with kdelibs-dbg

Sorry, my bad. I built kdelibs in Debug, but didn't install it (apparently, I still need to get the hang of pacman). 
Regenerating stack trace and will attach now...

backtrace is provided in comment #7.

Can you attach the output of solid-hardware list ?
Also, is this 100% reproducible?

Yes, this does seem to be 100% reproducible..
I think you're on to the right track in that one of my disk devices is causing the issue.

It seems that a CD in the CD drive causes the crash. Just ejected the CD that was in there, and the crash does not occur... I ripped it successfully the other day though, so it's not thaat scratched

Can anyone reproduce this crash everytime?

These crashes in libsolid are hunting us and the only reason why we have not fix them is because no developer can reproduce them :/

So if anyone is able to reproduce the bug, even if it is 1 out of 2 times we should have a IRC/Chat/something session to debug it.

If Bug 315472 is a duplicate i am able to reproduce the error. Feel free to contact me by e-mail:

*** Bug 315472 has been marked as a duplicate of this bug. ***

Till can reproduce, see comment #14.

i tried to reproduce it today, but it does not appear again. Nothing obvious has changed since then. I don't know why it disappeared.

amarok (2.7.0) on KDE Platform 4.10.1 using Qt 4.8.4

I had just been playing an audio cd in Amarok and needed to reboot the system after updates had installed.  
I left the playlist as it was and just closed down Amarok and rebooted the system.

When the system rebooted it automatically detected my audio cd was in the drive and it brought up the dialogue box asking what I wanted to do with audio cd.  I selected the option to play audio with Amarok.

Amarok opened up fine at this point and already had the old playlist in the right hand side of the Amarok window, however the playlist would not play, it also didn't show the audio cd in the left hand part of the window.  I thus used the browse options to see if I needed to re-select the audio CD in the right hand side of the Amarok window. 

It was during this browse process inside Amarok that I got the crash.

Generally for me Amarok plays Audi CD's fine except for it placing short periods of silence between each track as it plays them.

In this instance Amarok seemed to crash because it had the old playlist still in it's cache, but the Audio CD had yet to be fully accessible from Amarok it was not yet appearing in the right hand side of the Amarok window under the source list.

Because you do not have debugging symbols installed. Please do NOT report backtraces that do not at least have 2 stars. Also, as you can see from the already reported backtraces, and the fact the report is already CONFIRMED, it is not necessary to provide more information, we already have all what we need.

Ok, sorry for the mess :/

Alex: the above reporter says he can reproduce this every time, you might want to get in touch with him.

I also marked this as a regression, as it was introduced with KDE 4.10.x

I highly doubt this was introduce din 4.10.x since that code has been barely modified.

You are right, the first mention is in KDE 4.9.5 with Amarok 2.6.0, my bad

Created attachment 78907 [details]
New crash information added by DrKonqi

amarok (2.7.0) on KDE Platform 4.10.2 using Qt 4.8.4

- What I was doing when the application crashed:

1. insert a audio CD in the cd tray
2. Startup amarok
3. select the menu Amarok > Play media ... or type the shortcut Ctrl+O

*** Bug 318619 has been marked as a duplicate of this bug. ***

The code for KFilePlacesItem hasn't been modified either, so I guess the regression is caused by changes in upstream components (udisk, udev, whatever).

Looking at the backtrace, KFilePlacesItem tries to detect Audio CDs as follows:

    Solid::Device d = device();
    if (d.isValid()) {
            if (m_access) {
                return QUrl(KUrl(m_access->filePath()));
            } else if (m_disc && (m_disc->availableContent() & Solid::OpticalDisc::Audio)!=0) {
                QString device = d.as<Solid::Block>()->device();
                return QUrl(QString("audiocd:/?device=%1").arg(device));
            }
    }

The crash happens, because d.as<Solid::Block> returns 0, in other words, Audio CDs are no longer treated as block devices.

Failure of said cast can be easily detected, but the question is rather, if it's not a Solid bug, how the code needs to be modified to correctly get the audiocd:/ URL for the block device.

I'm using a pretty vanilla OpenSUSE 12.3 system at home.  When I click on file browser in Amarok, I get this related crash everytime:

Well removing an audio CD fixed the issue. I guess that's not surprising.

This is no preblem for me with kde 4.10.4 in kubuntu

> This is no preblem for me with kde 4.10.4 in kubuntu annymore.

Thank you for the feedback. Can the other reporters confirm this is solve in KDE 4.10.4 or later?

The code in kdelibs hasn't changed, so if it now works with an Audio CD inserted, upstream components have been changed. See comment #40.

Sadly, I can not confirm, with kdelibs 4.10.4 and amarok 2.7.1

Hopefully this gets backported to 4.10

Does this mean you tested it successfully? As indicated in the review request, I am unable to test.

Btw, there will be no further 4.10 releases, so distributions would have to apply the patch locally, if they plan more updates.

No, just a comment.

Would try it, but i don't have the time to recompile kde

It seems that this bug is patched in the latest amarok in opensuse.
Now amarok doesn't crash when selecting play media, but it doesn't play CDs.

Do you have a link to that patch? We for sure didn't release on for this issue, as it is not in Amarok, but in Solid.

Nope.
I just updated my amarok using package manager and bug is gone, but CD's don't play.

The cause of this bug is the same as bug 317485. Alex, you might want to close one of the 2 as a dupe of the other.

Meanwhile the crash above should have been worked-around in Amarok by:

Beautiful patch. I couldn't wait for the next release (I look forward to whenever it will be, though), so I just applied it to 2.8 beta sources.

Great work guys! Kudos to Matěj and Alex Fiestas!

Will close it once it is fixed properly in libsolid https://git.reviewboard.kde.org/r/111802/

New crash information added by DrKonqi

amarok (2.7.1) on KDE Platform 4.10.4 using Qt 4.8.5

- What I was doing when the application crashed:

- Unusual behavior I noticed:

- Get message "The audio playback device HDA ATI SB (ALC889 Analog) does not work.
Falling back to default." prior to crash.
