Description nothy 2009-11-20 16:23:18 UTC 
Application that crashed: amarok
Version of the application: 2.2.1
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.5.3
Operating System: Linux 2.6.26.8.tex3 i686

What I was doing when the application crashed:
If  open dolphin and click on a mp3 file Amarok 2.2.1 will crash after displaying the splash screen. Sometimes if I close out the crash display and click on the mp3 file again Amarok will launch and play the file.

If I open Amarok and I can select the same mp3 file from the menu and it plays fine

commit 45d4f4f4b92d73178551d4476258e024710cfac9
Author: Mark Kretschmann <kretschmann@kde.org>
Date:   Sun Dec 20 08:49:46 2009 +0100

    Fix potential crash on startup (0-pointer).
    
    This could happen if you started Amarok e.g. from Dolphin directly,
    for playing music. At the point where handleCliArgs() is processed, the
    MainWindow has not yet been constructed. Hence the crash.
    
    Please test :)

Comment 16 Texstar 2009-12-20 12:19:46 UTC 
I applied the patch to Amarok 2.2.1.90 and I get the bootsplash of Amarok, the music starts to play and thats it. Amarok never appears on the screen or in the system tray. I will try the patch with 2.2.1.
Comment 17 Myriam Schweingruber 2009-12-20 15:41:34 UTC 
Texstar, you don't understand: this is fixed in 2.2-git, just applying the patch to a much earlier version will probably not help, there might have been other changes in trunk since

Pasting BT from other report here (it's without debug symbols though -> fairly useless):

Comment 24 Myriam Schweingruber 2010-01-15 12:01:06 UTC 
Karel, if you can reproduce this, please install the debugging packages and see here on how to get a better backtrace:

http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Since you are using Ubuntu, you will need amarok-dbg and phonon-dbg at least, ideally you should also have kdelibs5-dbg, libqt4-dbg and  libglib2.0-0-dbg installed.
Comment 25 Myriam Schweingruber 2010-01-15 16:04:09 UTC 
Karel: are you absolutely sure you were using Amarok 2.2.2 final and not the beta version? Nobody can reproduce this here.
Comment 26 Karel Kozlík 2010-01-15 17:54:43 UTC 
 I tried to reproduce this again but neither I has been successfull with it. Ok I will install the debugging packages just for the case it will occur again. 

Yes, I am useing Amarok 2.2.2. It's from Kubuntu Backports PPA repository:
deb http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu karmic main
Comment 27 Myriam Schweingruber 2010-01-15 20:00:37 UTC 
Thank you for the feedback. Closing for now, feel free to reopen it if you can reproduce it with a valid backtrace for Amarok 2.2.2
Comment 28 felix 2010-01-17 20:36:03 UTC 
Created attachment 39986 [details]
New crash information added by DrKonqi

Still crashes while lauchning a mp3 from dolphin. 

Kubuntu lucid lynx - all updates.
Comment 29 Myriam Schweingruber 2010-01-17 23:22:16 UTC 
Felix, you are using Amarok on an Alpha distribution, I don't think this can be considered...
FWIW, I can't reproduce this here, using Amarok 2.2.3-git on Kubuntu 9.10, KDE 4.4 RC 1
Comment 30 felix 2010-01-17 23:50:36 UTC 
I added my backtrace cause you said "if one can reproduce..".

Lets hope it will be gone with release. I'll report in otherwise ;)

Comment 32 Texstar 2010-02-05 00:05:02 UTC 
Amarok 2.2.2 with KDE 4.3.98 RC3 when selecting a mp3 file from dolphin will display the Amarok splash screen and start playing the file but it never docks into the system tray. I guess we will need an Amarok 2.2.3 for KDE 4.4?

Amarok 2.2.2.90 works when clicking on a music file from dolphin in KDE 4.4.0. Excellent!
