Reproducible: Always

Steps to Reproduce:
1. Start Amarok (clean the config if repeated attempt). I'm not sure which particular conf caused it, but I removed all references to amarok from ~/.config/Trolltech.conf, deleted ~/.kde/share/apps/amarok/ and ~/.kde/share/config/amarok*
2. Configure plugins, enter Last.fm user/pass, press the [Check login], confirm/apply. Press [OK] on the main config window.
3. Profit.
Actual Results:  
Amarok crashed & burned.

Expected Results:  
No crash.

glibc backtrace, in case there's any use for it

*** glibc detected *** amarok: double free or corruption (out): 0x00007fffb0575fe0 ***

Comment 3 Myriam Schweingruber 2012-11-02 15:34:05 UTC 
Reproducible with any fresh install and whatever Internet Service one does configure, not related to last.fm. I had it with the Gpodder configuration.
Comment 4 Arne K. Haaje 2012-11-11 17:08:44 UTC 
Using Amarok 2.6 on Kubuntu 12.10 with KDE 4.9.3.

I can confirm Amarok crashes with last.fm enabled. When started from the console this error is output before the crash.

QMetaObject::invokeMethod: No such method App::onWsError(lastfm::ws::Error)
"
    Invalid API key - You must be granted a valid key by last.fm

"<?xml version="1.0" encoding="utf-8"?>
<lfm status="failed">
<error code="10">

If i disable last.fm in ~/.kde/share/config/amarokrc then Amarok start with no problem

Reassigning back to Last.fm. While more services may suffer from the similar error (whose cause is now clear to me), the code is not shared, so it needs to be reported for each service individually. The fix for Last.fm should land any time now.

Last.fm plugin: major rework of configuration and more

This work started as an attempt to fix bug 306134. I figured out that
the synchronous KWallet API is simply dangerous, and the async one must
be used. But that meant to make LastFmServiceConfig a "living" object
with updated() signal, which triggered refactoring of all its usage.

Users of LastFmServiceConfig now watch for its changes and should act
appropriately. The LastFmServiceConfig now has only one instance shared
between LastFmService and LastFmServiceSettings - I had to introduce
another shared library because KCM modules use separate library, silly.

Moreover, some extremely ugly things in Last.fm plugin got reworked to
me clean and maintainable, reducing code duplication.

Patrick, please tests whether this still builds on Windows, I hope I've
done KDE_EXPORT/KDE_IMPORT right, but I cannot test under Linux.

CHANGES:
 * When configuring Last.fm plug-in, the changes are now applied
   immediately in most places.

BUGFIXES:
 * Fix suboptimal KWallet usage in Last.fm plugin.
 * Fix crash in Last.fm plugin caused by sloppy KWallet usage.
