-------------------------------------

Hi Galder, community 5.1 release. 

Thats the problem, we cant replicate it easily, we cannot find the pattern. What I did this morning, I had started 2 nodes, created dirs and few files, then turned first then second off and on, then Michal joined in and when I tried to open one of the folders - voila exception happens. So the exception is thrown when it tries to get the content/properties? of the directory on opening.

> We ran into this when we were demoing gridFS webdav demo on the developer conference using Gnome's 'Connect to server' function and then accessing via Nautilus. Looks like error in webdav 3rd party lib.
