I use exiftool on OSX Lion. I have the latest version (8.75). I have the same error on cmd-line & in Perl-Module.
I try to write exif data in a .tif, but get always this error:
$ exiftool -GPSLatitude= film_7-01.tif
Error: [minor] Maker notes could not be parsed - film_7-01.tif
0 image files updated
1 files weren't updated due to errors
I'm pretty sure it worked some time ago!
This indicates that the maker notes are not recognized by ExifTool, and so there is a chance that some maker note information may be lost if the image is written, but adding the -m option allows you to ignore this minor error and write the image anyway. This is similar to FAQ number 15 (https://exiftool.org/faq.html#Q15).
If you want me to take a look, you can email a sample to me (philharvey66 at gmail.com).

Thanks for the sample. The makernote information is 130 bytes long, but it looks self-contained so if it does contain something useful, it should be preserved OK when rewriting with ExifTool. So I would say you are safe to use the -m option for this file.
