Description Jochen Bauer 2009-10-27 22:22:07 UTC 
Version:           2.2-git (using KDE 4.3.2)
Compiler:          g++ 
OS:                Linux
Installed from:    Ubuntu Packages

If I play a stream from last.fm Amarok plays one or two songs and at the end of one of them, right before the next song should start, it crashes. I just discussed this with jeffrai on irc. If I play Songs from my collection, amarok doesn't crash. 

Here is my Backtrace:

Comment 1 Dario Andres 2009-10-28 13:36:09 UTC 
- Is your build updated?
This looks like bug 200546 , which was fixed some days ago...
Thanks
Comment 2 Jochen Bauer 2009-10-28 13:52:12 UTC 
My build was from yesterday evening. Just did a completely clean build and trying again.
Comment 3 Jochen Bauer 2009-10-28 14:16:25 UTC 
After a full clean rebuild with deleting all am,arok folders, the thing doesnt happen anymore.

commit 06fe035e58d190706e949bcd8fa270f6311c107f
Author: Mark Kretschmann <kretschmann@kde.org>
Date:   Sun Nov 1 12:17:00 2009 +0100

    Enable C++ exceptions handling in Amarok. Fixes liblastfm crashes.

    Liblastfm is using exceptions for error handling. Since Amarok (like
    all KDE apps by default) was built without exceptions support, we just
    _crashed_ whenever an exception occured. Fixed. Additional bonus: We could
    use exceptions in Amarok itself now, if there is a need.

    BUG: 200546
    BUG: 212115
Comment 5 Mark Kretschmann 2009-11-24 08:52:37 UTC 
Reopening, as we are still experiencing issues. For reference:


"Qt has caught an exception thrown from an event handler. Throwing
exceptions from an event handler is not supported in Qt. You must
reimplement QApplication::notify() and catch all exceptions there.

terminate called after throwing an instance of 'lastfm::ws::Error'"

commit ca312861bac8be336623c04fd9cd9f164b452ba2
Author: Mark Kretschmann <kretschmann@kde.org>
Date:   Fri Dec 25 08:03:30 2009 +0100

    Try to fix Qt crashes when Liblastfm throws exceptions.
    
    According to Qt docs, the only way to do this is by overloading
    QCoreApplication::notify(). So we're doing that now. I don't know if it
    works, please give it some testing :)

    Try to fix Qt crashes when Liblastfm throws exceptions.
    
    According to Qt docs, the only way to do this is by overloading
    QCoreApplication::notify(). So we're doing that now. I don't know if it
    works, please give it some testing :)

Hm, the crash is still in Amarok 2.2.2, apparently, see the following duplicate

Comment 13 Leo Franchi 2010-02-14 17:33:37 UTC 
the marked duplicate crash is different, so marking as resolved fixed still.
