I don't think so. The FS should not care about the structure
of filenames. A lot of applications (web caches, news spools)
use similarly "hashed" filenames. If there was a problem with
them, it would certainly have been discovered much earlier.
Are you _sure_ that that filename in question does not contain
any spaces, tabs, control characters etc.? It seems to have a
space appended at the end, but that might be an artifact of
pasting it to the newsreader. But you should definitely check
this. It would certainly explain what you're experiencing.
Regards
Oliver
