To reproduce you need to use a demo webdav server available on Internet, you need to save a file to server first, remove it, then try to open using the direct link.

1) login at: http://demo.openkm.com/OpenKM/login, choose whatever user+password you prefer from the list given there; login and password will be used to access the server from LO;

2) load a test file of your choice into LO from your PC;

3) select 'File > Save to remote server' from menu;

4) add the new server to the list of available server using the 'Add service' button, using the following setup:

Host: demo.openkm.com
port: 80
root: /OpenKM/webdav/

confirm and input user and password of point 1)

5) navigate to okm_personal/<user name> folder, verify that the file name you intend to save does not exist in the folder

6) Select the file name edit box and hit 'Save' button;

7) close the file. Now the direct link should be available on LO start page;

8) using the web interface of the server, remove the file just loaded: select file, right button =-> delete

9) now try to open the file using the direct link on LO start page

10) LO should show the error '$file does not exist' but it doesn't.

This is caused by the solution I opted to solve bug 96669.
