Application: amarok (2.8.0) KDE Platform Version: 4.14.8 (Compiled from sources) Qt Version: 4.8.6 Operating System: Linux 4.1.15-gentoo-r1 x86_64 Distribution: "Gentoo Base System release 2.2" -- Information about the crash: - What I was doing when the application crashed: Both gstreamer-0.10 and gstreamer-1 are installed on my machine (using gentoo's SLOT system). I can't uninstall gstreamer-0.10 because many apps are not yet compatibles. It seems like pulse-gstreamer chooses gstreamer-0.10-x.so event if it was built against gstreamer-1. I am not sure this is the cause of the issue, but in all cases, when I launch amarok with plasma configure to use gstreamer, it crashes with the backtrace refering to /usr/lib64/libgstreamer-0.10.so.0 - Custom settings of the application: Built from sources, built against plasma-gstreamer, both gstreamer-0.10 and gstreamer-1 are installed. The crash can be reproduced every time. -- Backtrace: Application: Amarok (amarok), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".

Unfortunately you do not have debugging symbols, so the backtrace is pretty useless. FWIW: you should be able to use both 0.10 and 1.x versions, just make sure you follow the compile instructions carefully, and of course you need the plugins for both versions. For the backtrace, please see https://wiki.gentoo.org/wiki/Project:Quality_Assurance/Backtraces
Hi, Thanks for the answer. I do not understand why symbols did not show up, I had them in KCrash before sending the report... About my CMake options, I am using Gentoo's portage build system, I did not use fancy settings or anything. From what I see, only -DPHONON_BUILD_PHONON4QT5=ON when building phonon-gstreamer, all others are defaulted. I double checked and cmake finds gstreamer-1.0 at build time, but it really links to gstreamer-0.10 at runtime...

Well, you need to compile both Amarok AND its dependencies with debugging enabled, because there still are no debugging symbols for the phonon-backend-gstreamer, and the crash obviously happens there.
Hi, Thanks again, Behaviour changed a bit after rebuilding all dependencies with debug symbols (not sure why), it used to crash at amarok startup, now it crashes when I hit the play button after amarok shows up. In all cases, same behaviour: gstreamer-0.10 is used at runtime. I am starting to suspect a version issue in glib, or maybe this backtrace is not for the right thread?

Which phonon-backend-gstreamer version do you build? Starting from version 4.7.80, you need gstreamer 1.x, not 0.10 for the phonon backend. Current phonon-gstreamer-backend version is 4.8.2 AFAIK Anyway, the crash is very obviously happening in the gstreamer library, I wouldn't be astonished that this is due to a version mismatch. Reassigning to the phonon backend
Yes, I have phonon-gstreamer-4.8.2 Here is the complete list of versions, as you see, both gstreamer-0.10 AND gstreamer-1.6 are intalled: [ebuild R ] dev-libs/glib-2.44.1-r1:2::gentoo USE="dbus (mime) xattr -debug (-fam) (-selinux) -static-libs -systemtap {-test} -utils" ABI_X86="32 (64) (-x32)" PYTHON_TARGETS="python2_7" 0 KiB [ebuild R ] media-libs/gstreamer-0.10.36-r2:0.10::gentoo USE="introspection nls orc {-test}" ABI_X86="32 (64) (-x32)" 0 KiB [ebuild R ~] media-libs/gstreamer-1.6.2:1.0::gentoo USE="caps introspection nls orc {-test}" ABI_X86="32 (64) (-x32)" 0 KiB [ebuild R ] media-sound/amarok-2.8.0-r3:4::gentoo USE="cdda embedded handbook opengl utils (-aqua) -debug -ipod -lastfm -mp3tunes -mtp -ofa {-test}" LINGUAS="fr -bs -ca -ca@valencia -cs -da -de -el -en_GB -es -et -eu -fi -ga -gl -hu -it -ja -lt -lv -nb -nl -pa -pl -pt -pt_BR -ro -ru -sl -sr -sr@ijekavian -sr@ijekavianlatin -sr@latin -sv -tr -uk -zh_CN -zh_TW" 0 KiB [ebuild R ] media-libs/gst-plugins-base-0.10.36-r2:0.10::gentoo USE="introspection nls orc" ABI_X86="32 (64) (-x32)" 0 KiB [ebuild R ~] media-libs/phonon-gstreamer-4.8.2::gentoo USE="alsa network qt4 qt5 -debug" 0 KiB
I finally could fix the mess... turns out the problem is with qtwebkit-4.8.6, the library was loaded by amarok somehow (libplasma.so.3), and qtwebkit-4.8.6 loads gstreamer-0.10. amarok and phonon-gstreamer was using the wrong version of gstreamer and crashed. I have no idea how to fix this for good, maybe dealing shared-objects prorities? Not sure how to do that. My solution is to disable gstreamer from qtwebkit-4.8.6, qtwebkit:5 is fine AFAIK.

that dependency is not from Amarok, but from kdelibs. You need to make sure you check your dependencies thoroughly, I have no problem building Amarok 2.8.x on Kubuntu with KDE 4.14.2 at all. So maybe this questions should be addressed to Gentoo...
