[fixed] Crash dump when edit one of my materials

[oort]

I get the crash dump listed below when I try to edit one of my materials in a file. The crash happens after clicking Edit Material... I can edit all other materials in the file. May have something to do with a yafaRay material setting???

Thanks,
oort
