Description Nidal 2010-03-03 07:45:52 UTC 
Version:           2.2.2 (using KDE 4.4.0)
Compiler:          gcc-4.4 
OS:                Linux
Installed from:    Ubuntu Packages

Hi,

I have upgraded my kubuntu9.10 to kde 4.4(all using kpackage/apt only). After upgrading, amarok doesn't start up. It crashes and take me through the bug reporting tool which generates a report and at the end says the report probably not useful.  When I try to start the application by giving the command "amarok" from CLI, it crashes and display the following messages on the console. This behavior is consistent and was never able to get amarok up after the upgrade. I have reinstalled almost entire kde libraries and components including amarok and it does not help. Also, I have applied ALL the available patches and updates as of today( March 3, 2010). Nothing helped so far.

I am attaching the report generated by the kcrash as well as apport along with this. Would be more than happy to provide any further info on this if asked.

Quick info,

Laptop: ThinkPad T400
OS: Kubuntu 9.10
KDE: 4.4.1
Amarok: 2.2.2

I have reported the same to Kubuntu bug tracking system too. Because I am not sure which one is more suitable. My apologies in advance if I am wrong to do so.

Thanks indeed,
Nidal

This looks like a bug in Phonon, but you should install the phonon-dbg package to get a better backtrace:

Application: amarok (2.2.2)

The crash can be reproduced every time.

Many many thanks indeed for the prompt reply ! I installed the phonon-dbg and repeated the same exercise. It still says "The crash information is probably not useful". Anyway I am attaching the latest crash report along with this. Please let me know if you need any further input from me.

Thanks a lot again !

Comment 6 Myriam Schweingruber 2010-03-04 14:31:49 UTC 
Indeed, it doesn't really help. Could you please start Amarok from a konsole with 'amarok -d --nofork' and see, if the next backtrace is more useful?
Comment 7 Nidal 2010-03-04 16:11:40 UTC 
Many thanks indeed for your persistence! But I had tried this too earlier and result was the same. Anyway I am copy-pasting the output of that too, in case you can make out anything out of it.

Please let me know if there is anything else I can help you to help me :-)

Thanks again,
Nidal

Comment 8 Evert Vorster 2010-03-10 07:12:48 UTC 
I get the same crash on amarok. 

Weird thing is that I only get it with a new user. 
When I copy all the files from an existing and working user, amarok works fine. 

-Evert Vorster-
Comment 9 Evert Vorster 2010-03-10 07:14:41 UTC 
OK, I just got it to work. 

I changed backends from Xine to Gstreamer in KDE for the new user, and now amarok starts fine. 

-Evert Vorster-
Comment 10 Nidal 2010-03-10 08:54:49 UTC 
Thanks a lot for your tip. Even I changed the backend to Gstreamer and Amarok works now. Will stick with this until the issue is fixed.

Thanks again to both of you,

Nidal
Comment 11 Myriam Schweingruber 2010-04-04 18:20:46 UTC 
OK, closing this report for now then. We are currently working on a new backend that should solve many of the existing issues, but this will still need some patience as it is only in it's alpha stage
