This is no crash. You used ps2pdf, that means that first a Postscript file is generated, and that can only contain EPS images. So it should work when you use pdflatex instead of ps2pdf, or when you use an EPS image. (For normal images, LyX automatically transform the image formats, but for the preamble you are responsible.) Btw. you should better use a relative path, because your document becomes uncompilable when there is no path "/Users/christiaanpauw/Pictures/" on another Computer.
