Description Emmanuel Benoit 2009-11-17 16:22:50 UTC 
Application that crashed: amarok
Version of the application: 2.2.1
KDE Version: 4.3.3 (KDE 4.3.3)
Qt Version: 4.6.0
Operating System: Linux 2.6.32-4-generic x86_64
Distribution: Ubuntu lucid (development branch)

What I was doing when the application crashed:
When I launch Amarok, I see the window appear for a very short while, after which it disappears and a SIGSEV follows. When launching it with --debug, the last few lines I see are:

Comment 1 Dario Andres 2009-11-17 16:29:28 UTC 
It looks like a QtScript / Qt java|ecmascript implementation to me.
- Have you manually installed Qt4.6.0 ?
- Do you know if Amarok was compiled against Qt4.6.0 or Qt4.5.x ?
Thanks
Comment 2 Emmanuel Benoit 2009-11-17 16:36:55 UTC 
No, I have not installed QT manually, I am using the version that comes along with (K)Ubuntu Lucid Lynx. According to qtconfig's "about" dialog box, it is version 4.6.0, however the package that contains the library is marked as "4.6.0 beta1".

I have no idea which version of QT Amarok was compiled against, but I could try getting the package's sources and rebuilding it, see if that helps.
Comment 3 Dario Andres 2009-11-17 16:38:44 UTC 
If the amarok package came from the same repo as the Qt4.6.0 package, then it should be compiled using it.
In any case, today Qt4.6.0rc1 was release, may be it will appear soon in the repos and you can test it.
May be an Amarok developer has a better opinion on this. 
Regards
Comment 4 Emmanuel Benoit 2009-11-17 16:42:54 UTC 
Yes, I just checked the Amarok package, it's been compiled with the correct version of the QT packages. My attempts at rebuilding it have failed so far, tho. I'll insist a little more.
Thanks for your time and effort.
Comment 5 Myriam Schweingruber 2009-11-17 19:04:46 UTC 
Do you use any external scripts in Amarok?
Comment 6 Emmanuel Benoit 2009-11-17 19:08:49 UTC 
I did, and rm -rf'ing them from ~/.kde/share/apps/amarok/scripts "solved" the problem, as Amarok now starts correctly.
Comment 7 Emmanuel Benoit 2009-11-17 19:15:39 UTC 
Oh, forgot to mention that the script which caused the crash was UltimateLyrics.
Comment 8 Myriam Schweingruber 2009-11-17 19:21:10 UTC 
Thank you for your fast answer. You should report this crash to the script author. Since this is a third-party application, there is not much we can do about that.
Comment 9 Emmanuel Benoit 2009-11-17 19:27:20 UTC 
A *script* causing an application which interpretes it to crash may be buggy in itself, but the crash indicates a bug in the application. However, as Dario pointed out, it is likely not related to Amarok itself but to the {ECMA|Java}script implementation in QT 4.6.0 beta 1.
Comment 10 Myriam Schweingruber 2009-11-17 19:45:35 UTC 
Emmanuel, there are several reasons this is not an Amarok problem:
a) the crash is in Qt,
b) Qt 4.6 has only just arrived in RC, I bet your version is the beta one and there are several known bugs in Qt 4.6,
c) Amarok depends on Qt. 4.4, not on 4.,6
d) You are apparently using Lucid, which is pre-alpha and potentially highly unstable and not for productive use.

Please report this bug to Qt or on Launchpad, but not here, there is noting we can do about this.
Comment 11 Emmanuel Benoit 2009-11-17 19:48:24 UTC 
I know, that's why I didn't reopen the bug report.
Comment 12 Emmanuel Benoit 2009-11-17 19:49:01 UTC 
Oh wait, I actually did. Sorry.

New crash information added by DrKonqi

Amarok does not start at all after upgrading to 10.04. It crashes immediately without showing any window and this happens both when computer starts (after kdm log-in) or if I attempt to launch it manually.
No user activity was running

Problem solved!! (at least in my case)
I just deleted all rc files concerning amarok in .kde/share/config/ so that amarok recreated a new set. These files are: amarok-appletsrc amarok_homerc and amarokrc.
Thank you to everybody
