/usr/bin/kcmshell4 kcm_phonon constantly crashes on window close, 100% reproducible for me. But other applets like powerdevilactivitiesconfig or powerdevilglobalconfig works as expected, and so does "audio video settings" when launched from system settings. Actions performed in the app doesn't matter, reproducible with simple open-close pattern. KDE 4.14.0, SysSettings 4.11.11 Reproducible: Always Steps to Reproduce: 1. /usr/bin/kcmshell4 kcm_phonon 2. close the window 3. enjoy sigsegv Actual Results: Kmix -> settings -> audio setup - always crash direct launch from lancelot launcher or terminal - always crash system settings -> multimedia - works as expected Application: KDE Control Module (kcmshell4), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

systemsettings 4 is no longer supported, we do only support version 5 I can not reproduce this crash with the following combinations systemsettings 5.4.1 + Qt 5.5.0 systemsettings 5.3.2 + Qt 5.4.1 Can you still reproduce this hang on version 5? If you can still reproduce the crash could you please install valgrind and then run valgrind systemsettings5 in a terminal, try to reproduce the crash and add here the valgrind output?
