+Summary: crash when passing struct to native code on ppc32
+http://bugzilla.gnome.org/show_bug.cgi?id=336758 is an f-spot bug that only
+happens on ppc32 linux.  It appears to be caused by passing a struct
+containing three doubles
+public struct ColorCIExyY {
+	public double x;
+ 	public double y;
+ 	public double Y;
+to a native function.  kangaroo did some digging and said this.

+(13:27:46) kangaroo: //* set the next to 0 once inssel-ppc.brg is updated */
+(13:27:46) kangaroo: #define PPC_PASS_STRUCTS_BY_VALUE 1
