Dear Maintainer,

the properties dialog of a davfs share in nautilus keeps counting files until
finished, then starts over without stopping.

To reproduce do
- start nautilus
- mount a davfs share
- enter the share folder
- press Ctrl-A to select all files (try this for several levels in the files
system hierarchy; the bug only happens at some levels)
- right mouse click the selected files
- select "properties" from the mouse menu
- the dialog keeps counting files forever


I could somewhat nail the bug occurence down to the following situation:

I have a webdav share folder /foobar/xyz/ which itself contains the folders
a,b,c,d,e,f. Properties of every single folder alone work fine, but selecting
folders b and c together and choosing the properties dialog leads to a
neverending counting. Folder b contains jpg pictures, folder c contains pdfs
and odt files.

There are no double file names, no hidden folders, no non-ascii characters in
the file names.

thank you,
Oliver
