Actually it was/is a Windows thing. Windows used to limit tke length of file paths to 256 characters. It eventually changed to remove that limit (likely doing like Unix right now, 256 characters per component), but you have to use a new API to see this. If you use the old API, for compatibility Windows silently drops the files that are too long instead of returning an error.
The GTK compatibility layer that Gimp uses to run on Windows hasn't been updated for quite a while and is likely still using the deprecated API.
