Description Sergei Andreev 2010-01-28 22:19:07 UTC 
Application that crashed: amarok
Version of the application: 2.2-GIT
KDE Version: 4.3.5 (KDE 4.3.5)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-18-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
Amarok suddenly crashed when there was high CPU and IO activity - KTorrent was allocating 11 GiB of harddrive space. But I am not sure this was the reason.

 -- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault
The current source language is "auto; currently c".

@KNotify devs.
Is this fixed in knotify from KDE4.4? I don't get these crashes here.

Offending code:
    Meta::TrackPtr track = The::engineController()->currentTrack();
    if( track )
    {
        if( m_notify )
            m_notify->close(); // Close old notification when switching quickly between tracks

        m_notify = new KNotification( "trackChange" );

        if( track->album() )
            m_notify->setPixmap( track->album()->imageWithBorder( 80 ) );

        m_notify->setTitle( i18n( "Now playing" ) );

        m_notify->setText( Amarok::prettyNowPlaying() );
        m_notify->sendEvent();
    }

    A safer approach for closing the notification. Avoids dereferencing a
    dangling pointer. I don't get crashes anyway but this may fix it.
