xgif doesn't install it's own X color map - that means it is trying to
allocate all of it's colors out of a map that already has several
colors allocated - on a 16 color display that means that there aren't
many colors left - xgif just goes on reducing the color resolution and
trying to allocate colors until it either succeeds (probably with a
very badly distorted color palette) or fails and gives up.

If you only have a 16 color display you really need to modify xgif
to install it's own color map even if you only want to display 16
color images.
