Some symlinks are wrongly detected as directories during scanning, e.g.

Maybe only the logging is broken. Trying to reproduce the issue, I find that the
scanner doesn't enter the symlinks into the database and it doesn't try to follow
the "directories".

There are 3771 files in the directory, and only 24 of those are not symlinks. But
the scanner finds them correctly. It doesn't try to follow false directories and is
finishes scanning in less than 1 second:

poeml@doozer2 ~ % rsync rsync://mirror.opencsw.org/opencsw-full/beanie/i386/5.11/ |
grep -v lrwxrwxrwx | wc -l
