Description Jonas Eriksson 2009-03-22 21:59:03 UTC
Version:           0.10.0-1ubuntu~intrepid~ppa1 (using KDE 4.2.0)
OS:                Linux
Installed from:    Ubuntu Packages

I've just upgraded my 0.94 to 0.10.0, by using Synaptic and PPA packages. This problem may be related to 187429. I have also tried complete remove of 0.10.0 and install again.

After reboot I can start digikam - no crash:

digikam(6401) Phonon::KdePlatformPlugin::createBackend: using backend:  "GStreamer"
virtual bool Phonon::Gstreamer::AudioOutput::setOutputDevice(const Phonon::AudioOutputDevice&) "default" 
Starting to load Plugins. 
Files:  "CompassFloatItem.so" 
Files:  "MapScaleFloatItem.so"
etc.

After closing digikam and start again - crash:

There is something fishy with that Phonon, as there is so much output with those lines when digikam craches.

Any hints of how to resolve this?

Comment 1 caulier.gilles 2009-03-22 22:03:21 UTC
No clue from us, digiKam team about phonon

I move this report to KDE phonon component where right developers can help you...

Comment 2 Pino Toscano 2009-03-22 22:17:58 UTC
There's nothing that says that the problem is in Phonon. Moving back to digikam.

@Jonas Eriksson:
can you please provide a backtrace of the crash?
You can find detailed instructions in:

Comment 3 Jonas Eriksson 2009-03-23 07:07:20 UTC
I will try to install debug packages tonight.

Kopete phonon crash-log

This crash comes after trying to play a notification sound in the notification properties.
Comment 5 Jonas Eriksson 2009-03-23 17:10:26 UTC
Argh... adding an attachment file removed my whole comment!

Well, what I had written was that this problem indeed has to do with phonon.

I have no problems playing sounds in GStreamer properties or elsewhere.

Comment 6 caulier.gilles 2009-03-23 17:19:30 UTC
Pino,

In digiKam, we don't do anything special with phonon. We just embeds the widget to play video file. that all.

Sure, but there was nothing more than output to say what effectively the problem is. _now_ that we have a clear backtrace, we can reassign it to phonon.

*** Bug 187959 has been marked as a duplicate of this bug. ***
Comment 9 Jonas Eriksson 2009-03-26 18:46:41 UTC
I read something about killing the kded4 process, so I tried it and then there is no crash when starting digikam or playing notification sound in kopete. If I start the kde4d process again and then starts digikam it crasches.

I don't know how import the kded4 process is to all kde-programs though...
Comment 10 Jonas Eriksson 2009-03-27 20:13:24 UTC
My latest solution to this problem is to remove phonon-backend-gstreamer and install phonon-backend-xine instead.
Comment 11 Myriam Schweingruber 2009-11-08 15:12:38 UTC
Does this still happen with the latest KDE 4.3.3?
Comment 12 Mathias Lindner 2009-11-08 16:12:43 UTC
No, it was fixed quite fast after reporting.
Comment 13 Myriam Schweingruber 2009-11-30 13:42:07 UTC
Thanks for the feedback. Closing then :)
