I modified /etc/bluetooth/audio.conf and removed "Socket" from the line in General: Enable=Gateway,Source I am not certain but this seemed to fix the problem. The setting now sticks.

If someone can reproduce this. Please run `kdebugdialog` and activate all debug output, then in a terminal run `kcmshell4 phonon &> ~/kcmphonon.log` and try to trigger the crash. Afterwards a file called kcmphonon.log will be in your home, please attach it to the bug report. Then you can deactivate debug output in kdebugdialog again. Dev Note: s_context is null which may be because PA crashed and we don't support reconnection or because init failed (and from a quick glance it does not seem like AudioSetup is protecting at this case actively though supposedly you should have no profile/card/etc to select in that case).
Git commit 866fb7334c3a011eb81cfd5492d8976d119f1a6e by Harald Sitter. Committed on 26/10/2013 at 14:13. Pushed by sitter into branch 'KDE/4.11'. Prevent KCM crash after a context goes bad If AudioSetup cannot connect to the context at construction the entire tab will simply not be added, so the KCM cannot crash on nullptr access in that case. However when a context goes bad after initial connection the KCM did not try to reconnect which pretty much ensures a crash on s_context=0. Connection logic was refactored into af function and used to attempt a reconnect. Additionally when failing to connect to the context the widget is now disabled, so even if the reconnect fails the user can not crash AudioSetup (also without a context the widget is useless).
