From John Ivar Haugland and Michael Platings,

JIV:"I deleted a line from the ReaderWriterDAE.cpp file that was introduced in rev 11341. I got a crash on this line when the options pointer was NULL."
MP:"Good spot John. The next line is also unnecessary and can be removed as well (attached, plus some minor code beautifying)"
