But atleast if one asks colormap from a drawable and then rendrers
a pixbuf from pixmap with the colormap in question it works like charm.

Have a look at desktop sources for this. There backround picture
is set this way.

True that backround picture is a different case since it is the
backround of an X window.  So if one fails to use right colormap
for backround, setting it from 32 bit image fails.

Could it be that you have similar case in your code?
