Seems to work fine here though I only have a couple of channels open. Are you getting a trp file? Is it crashing in an xmms register? And of course, what CPU, there's cpuinfo.zip on Hobbes to get all the CPU flags, handy for comparing which extensions are supported and at least one Phenom user had a sigill as Phenom supports SSE4a but not SSSE3 while my CPU is the opposite.
I don't know how to read the trp file but it does create one... it crashes in xul.dll on an invalid address is all I can tell for sure. Here is the cpu information from cpuid and cpuinfo and a few lines from the trp files that seemed to stand out to me as maybe helpful. I can send the whole thing if useful.
