Just thinking aloud:

"Opening directory", "no such file or directory",
 >> | "/home/shamrock/webs/mydomain/.#index.org"

is exactly what grep always gives me in such e case (I often use
`grep -lFr string dir').

sh> ls -l /home/sebastian/notes/.#index.org
lrwxrwxrwx 1 sebastian sebastian 31 26. Okt 22:27 
/home/sebastian/notes/.#index.org -> sebastian@orgon.4849:1225047914

That means .#index.org is a link pointing to a non existent file.
4849 is the process (cat /proc/4849/cmdline), that edits the file
/home/sebastian/notes/.index.org, so it indeed seems to be a locking
mechanism.

Problem seems to be, that the error occurs when ever trying to
access the file, which simply can not work, since it's a link
pointing nowhere.

org-publish-get-base-files-1 excludes files, whos names consist entirely
of dots:
	(not (string-match "^\\.+$" fnd))

Maybe exclude files like 'sebastian@orgon.4849:1225047914'
too - hm - a totaly legal filename though...

Or extend the file-test, so it doesn't simply test for names, but
additionally tests for

'is it a file OR (is it link that points to a real file)'
