Do those complaints include the one that says this:

  gdk_pixbuf_new_from_data: assertion `bits_per_sample == 8' failed

What's so special about IDL mode that it causes this?  Ah, I see: it
comes with its own XPM images for the toolbar (in idlw-toolbar.el),
right?  If that's the reason, can we somehow modify those XPM icons to
use only 8 bits per sample?

Thanks.
