Well, you can at least tell in what circumstances this was happening, what application you were running, was this on startup? Without a little more information we will not be able to reproduce this. FWIW: currently, you should use the gstreamer or vlc backend instead of the xine one, as those are much more stable now.
OK your comments about gstreamer, VLC and xine means that I was trying to get my Intel sound h/w working under Kubuntu 11.04. Probably working under the system settings trying various options for the h/w options. had 2 sound systems. The Intel chips resident on the motherboard and a Hauppage TV tuner card. as the following info on it: WinTV-HVR-1600. The computer specs describe the motherboard chips as: "SigmaTel 9223 High Definition Audio Chipset". In versions of Kubuntu previous to 10.xx, both sound systems worked and I was able to set output to the motherboard chipset. In Kubuntu versions 10.xx the sound system output worked, but the Line In socket did not. In Kubuntu 11.04, the sound output also stopped working. It was suggested that I remove the Hauppage board. That got both the Line In socket working and sound output working. So my guess is that the KDE sound s/w is having a hard time if ,ore than 1 sound system is present. Maybe especially if one sound system is in a TV tuner board?? In trying to get things working I downloaded and set both Xine and VLC to the Phonon backend. Neither made any difference and I have restored gstreamer as the operational backend. Anyway, it was during the struggle to get sound (both input and output) working that the crash occurred. Exactly what I was doing is a mystery lost from my memory totally. I probably could not have told you immediately when the crash happened since in the process of trying various options, exactly which option was under consideration was not something I was documenting or keeping diligent track of. Hope this additional info is helpful as it pretty much is all I can supply.
