Is it related to the presence of two "."s in the name?
I do recall there being issues with such names back in the good old days of MSDOS 8.3 names (which didn't actually allow "." in the name, it just displayed it between the 8 and 3 part).
But, from what I read above, this seems ot be an issue with removing the original, rather than creating the new entry, so....
PS: I've correct the typo in the title.
