I agree with you for the reason that makes kmmfiles to work. It's because the parser doesn't use CR-LF but ; to know where is the end of the line.
But for the bug, K-Meleon just knows CR-LF for kml files, and use it to know the end of the line.
To make it work, I have used PsPAd to convert LF to CR-LF line end.
Just the opposite of what you said
