[Zope] Zope + WebDav + davfs and vim

Hi. Has anyone run successful Zope with davfs? I have problems when i try edit and save some files or when i try create new files. I have also problems with Zope and curlftpfs. When i save one file and then i try edit others it doesn't work (i must kill vim and curlftpfs). Debug doesn't say where is the problem...
