After enabling the OpenGL spectrum analyser, when disabeling it xmms 1.2.9 crashes. If xmms has been shut down normally and restarted since the OpenGL spectrum analyser was enabled it is impossible to disable it without editing the ~/.xmms/config file since every atempt to disable it crashes xmms and when rerun ing it the OpenGL sepctrum analyser is enabled. When enabling and disabling the OpenGL spectrum analyser in the same run of xmms it still crashed but when rerun the OpenGL spectrum analyser isn't enabled. Strace output suggests it might be a bug that has to be filed upstream but my knowledge in this area isn't good enough for me to be sure. Reproducible: Always Steps to Reproduce: 1.Enable OpenGl Spectrum Analyser 2.Disable OpenGl Spectrum Analyser or Close xmms rerun xmms and disable OpenGl Spectrum analyser Actual Results: Xmms crashes and the OpenGl Spectrum analyser can't be disabled if xmms has been closed and rerun in the mean time.

Looks like this bug has been reported upstream to the Xmms bug tracking system too so i guess it can be considered an upstream bug.
Sorry for the constant flood, these are references to the bug in the xmms bugzilla: http://bugs.xmms.org/show_bug.cgi?id=1386 http://bugs.xmms.org/show_bug.cgi?id=1564
