OpenSlideError: 00000000: expected a marker instead of 4880

[Toby Cornish]

We are converting a number of SVS files to DZI using openslide and the python deepzoom_tile.py script.

All of the files tried so far work, but one file gives us an 'OpenSlideError: 00000000: expected a marker instead of 4880'

This is an SVS JPEG2k/KDU file with embedded ICC and label, macro, thumbnail.  Any thoughts?

Thanks, Toby
