One other idea is to compare the XPM images in idlw-toolbar.el with
the ones we have in etc/images/, and see which part(s) of the
differences between them cause the problems.  I'm not an expert on
XPM, but I see a few differences, besides the color depth.

Btw, when you changed #000000000000 to #000000, did the error messages
from GdkPixbuf about 8 bits stop?

The messages from GdkPixbuf about 8 bits (gdk_pixbuf_new_from_data: assertion 'bits_per_sample == 8' failed) are still present with colors changed to #000000. Attached is the backtrace, and the idlw-toolbar.el file I used.
