A minimal example can be created with the following command:
$ printf 'P6 1 1 255\n\0\0\0' tmp.ppm
The problem here is distinguishing between a pbm, which cjb2 will
convert, and ppm, which it will not.
Imagemagick identifies them both

The 'class' attribute can be used to distinguish between those types:
$ identify tmp.pbm; identify tmp.ppm
tmp.pbm PNM 1x1 1x1+0+0 PseudoClass 2c 1-bit 8b
tmp.ppm PNM 1x1 1x1+0+0 DirectClass 8-bit 14b
Thanks for this. In the mean time I had come to

Trying to save a non-bitonal image as DjVu triggers an error:
Not true in general, however. You can import, say, a JPEG, and save it
as DjVu perfectly well.
If you have an image which you can import and saving as a DjVu
produces this error, please attach

Trying to save a non-bitonal image as DjVu triggers an error:
Yes. This is highly annoying - caused by imagemagick writing a 1-bit
image as 8-bit and djvu not accepting it.
