Check /local/grassdata/lovenia/PERMANENT/fcell as well.  All fcell files
also have a zero byte "place holder" file in the cell directory. Or, in
other words, all raster files regardless of data type will have an entry
in the cell directory.

Yes, there was an oops that got committed just before the sources were
tagged and checked out.  It's fixed now (I understand).

Hmm, Did you run r.compress -u using old version?  Then, without
recompression, was new version able to read them?

You don't want to recompress with the old version.  You want them
uncompressed *before* running the new version.  You can recompress them
with 5.0beta11 and everything should be okay (but older versions won't
be able to read them).

Perhaps, instructions were not clear enough.  We're sorry for the
problem, but we don't have any choice in the matter.
