could you please install the debugging information for phonon and try to get a new backtrace? Might be a problem with phonon, not with Amarok. Created attachment 82698 [details]
New crash information added by DrKonqi
amarok (2.8.0) on KDE Platform 4.10.5 "release 1" using Qt 4.8.4
- What I was doing when the application crashed:
Played audio file, during which I fetched an album cover by right mouse clicking in main window. Playback paused twice, I assume reloading album cover, then stopped on its own. At that point, I closed Amarok (was trying to induce crash after installing Phonon debug symbols)
- Unusual behavior I noticed:
Playback stopped for at least five seconds, did not resume before I closed program (which generated crash)
-- Backtrace (Reduced):

Thank you for the fast feedback, that is what I expected, the crash is in Phonon. Reassigning. Amarok bug. VFE gets destroyed #13 0x00007f2629444d8f in ~VolumeFaderEffect (this=0x1871340, __in_chrg=<optimized out>) at /usr/src/debug/phonon-4.6.0/phonon/volumefadereffect.h:50 VFE cleans up its QObject children #11 0x00007f262d0674c2 in QObjectPrivate::deleteChildren (this=this@entry=0x1871f10) at kernel/qobject.cpp:1916 One of them is Fadeouter #10 0x00007f262ed8a789 in Fadeouter::~Fadeouter (this=0x40cd000, __in_chrg=<optimized out>) at /usr/src/debug/amarok-2.8.0/src/playback/Fadeouter.cpp:54 Fadeouter tries to call the same VFE's ::fadeTo #8 0x00007f2629444a4a in Phonon::VolumeFaderEffect::fadeTo (this=<optimized out>, volume=1, fadeTime=300) at /usr/src/debug/phonon-4.6.0/phonon/volumefadereffect.cpp:75 You are now within a half destroyed VFE. Crash because VFEPrivate has already been thrown away so vtable lookup ends up in garbage, resulting in SIGSEV #7 0x00007f262942f038 in Phonon::MediaNodePrivate::backendObject (this=0x1879d40) at /usr/src/debug/phonon-4.6.0/phonon/medianode.cpp:63 *** Bug 328889 has been marked as a duplicate of this bug. *** Git commit 8804bf898122bf4e23b3d7660bad448759f34066 by Matěj Laitl.

Pushed by laitl into branch 'master'. playback: fix crash on quit in the middle of a fadeout My assumption was incorrect, a child must still track its parent using QWeakPointer to be safe.
