In the palettize function when the PaletteCreationMode Uniform is used, in the corresponding function uniformQuantization when maxCols is less than 8 this causes bitDiv3 to return 0 as at least one element of the tuple (bg, br, bb) which then causes the corresponding list to evaluate to [0, 0 .. 255] which will never terminate.

In my case, this causes the program to use 100% of the CPU filling up the RAM until the system hangs.
If values of less than 8 are not considered valid then this should be at least mentioned in the documentation or there should be a check of some sort.
