Bug description:
Binary package hint: gtk2-engines-qtcurve

when calling common/common.h:rgbToHsv with rgb equal and so max == min means delta is 0 causing a divide by zero segfault. attached is a possible fix although there may be a better one it should be fairly reasonable

Program received signal SIGFPE, Arithmetic exception.
