When running KDE4 over NX, there seems to be a problem with the xine plugins.
No plugin is loaded and this triggers an assert in Phonon, causing a crash.
What should happen is that Phonon should check for the module and fail gracefully.
It show a yes/no dialog saying: You audio setup is faulty. Do you want to switch off audio?
Since this crash happens over and over, the only viable way out is to switch off audio notifications, but even then, phonon might crash whenever an application tries to play a sound via phonon.


Application: KNotify (knotify4), signal SIGABRT
