}

Notes:

1. if you share welcome.txt from nc to oc, and oc has a file named welcome.txt in the same directory, your share will be named welcome (2).txt, when you click on the share from oc, it tries to access welcome (2).txt in nc which doesn't exist.
2. above point is a bug itself, but it really doesn't matter, create a file with a different name in nc that doesn't have any same-name counterpart in oc, share it with oc, try to access it from oc, and you'll see the same webdav error.
3. it works fine for folders.

it actually calls remote.php/welcome (2).txt

I opened an issue about this in owncloud/core a few months ago, I’ll link it
Maybe it should open remote.php instead of public.php?
