AFAIK the xpm format does not make a difference between "indexed" and
"rgb". From the xpm point of view everything is indexed - with an
arbitrary number of colors.
With a small number of colors it assigns every color an character -
you can easily understand the format if you read an xpm file.
However with this you run into problems if you have more than ~ 100
colors, because then you would have to use nonprintable/non-ascii
characters. So the xpm-format can use strings (of the same length)
for different colors: "aa" could be red, "ab" green etc.
So the strin "aaab" would mean a red and a green pixel.
I believe this is standard, this bug should be fixed in KDE.

Simon
