So after some days of hacking, I now present my own MakerNote removal tool: http://anders.hultman.nu/data/makernote/
I found and corrected a coding error yesterday, so now there is a new version on the above page. In the old version (0.9.0) I didn't adjust the offset value to the thumbnail image properly, so programs that show you the in-file 160x120 pixel image couldn't find it even though it was there. This is fixed in 0.9.1.
Next thing to examine is why it crashes on Olympus camera images.
