Can't open certain .PSF files

[Drahken]

Xnview 1.74 can't open .PSF files when they were saved at 100% quality. Oddly, ones that were saved at 99% quality (or less) work fine. I don't know much about the .PSF format, but I'm assuming that 100% quality is lossless and that xnview can only handle lossy PSF files.
Here are 2 examples:

The quality=99% one will work fine in xnview, but the quality=100% one gives a "unknown format" error, and can't be opened.
These images were created with polaroid photomax pro 2.0, if that's of any help.
