Error 404/409 on PROPFIND options => path

Hi,
i get 404 Errors on Directories with a linux webdavclient like cadaver or davfs.
with a normal windows network connection everything works fine.

i figured out with module trace that in the options array the path in windows is 'path' => '/myfolder'
but with linux/unix it is 'path' => '/myfolder/'

so after i remove the trailing slash with rtim() i fixed that error for my linux webdav clients.

id do something like that in the file dav.inc near line 409 function PROPFIND()

$options['path'] = rtrim($options['path'], '/');
.....
$path = _dav_explode_path($options['path']);

im working with the modules fileframework and fileserver with file taxonomy server enabled.
maybe the problem could also come from these modules.
dont no!
