This warning still being present in master was a bug. Scaling; along
with gaussian blur, unsharp mask, rotation, flattened down text layers
and more ops, now treat indexed mode in such a way that if the palette
contains relevant entries for desired in-between colors the scaling
code in GEGL, and thus GIMP uses them.

The warnings is now gone in master, to get the old result - of course
nearest neighbour can be chosen manually :).

With greetings Øyvind Kolås

All right.

Regardless, some sort of warning when saving an image with transparency as JPG would be user-friendly.
