I have reduced this somewhat by instrumenting the xattr library.
{{{
import xattr
xattr.getxattr("data/Documents/calendars","user.{DAV:}getcontenttype")
}}}
Will throw the same IOError.
Running caldav as root gets around this xattr problem but memcached
doesn't run. (Which also breaks the server. No pages load.)
