This is interesting. How did you create the B&W images? They seem to have an embedded color profile that ICE isn't able to convert to SRGB required by jpeg. I think that this should only affect the Plubish to Photosynth process,
you should still be able to 'Export' to a tiff or other format.
I'd be interested in taking a look if you can share the original images somewhere so that we can download them.
