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 :)

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.

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

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.

Karel: are you absolutely sure you were using Amarok 2.2.2 final and not the beta version? Nobody can reproduce this here.

 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

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

New crash information added by DrKonqi

Still crashes while lauchning a mp3 from dolphin. 

Kubuntu lucid lynx - all updates.

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

I added my backtrace cause you said "if one can reproduce..".

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

*** Bug 225530 has been marked as a duplicate of this bug. ***

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?

*** Bug 225612 has been marked as a duplicate of this bug. ***

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