Bug 87365

Description:
After opening a document as a copy, LibreOffice appears to treat it the same as a completely blank untitled document.  

To keep your LO windows uncluttered, when you open a document, LO will attempt to reuse a completely blank unmodified document that you currently have open.  Since you have made no changes to it, it will close your unmodified document and taking over that window.

Unfortunately, when you open a document as a copy, LO apparently isn't setting a modified flag, so LO treats it exactly as it would a blank document.  It reuses the window and clobbers your copy.

Steps to reproduce:
1. Open a file as one user
2. Attempt to open the same file as another user
3. Choose "Open Copy"
4. Immediately do File->Open and open another document (as second user)

Expected:
Both the copy of the file in use and the new file should be open, in different windows.  

Actual:
The copy has been completely lost with no way of easily reopening it.  Because it actually opened the new document, it closed our copy with no way to undo.  And because of bug 85325, it doesn't even show up under recent documents.

It's easy to work around once you know what's happening.  Simply insert a space or make any type of modification to your document, and it will be safe from clobbering.

Unfortunately, this bug has been around since before LO.  I was able to reproduce this using OpenOffice 3.2.1, so I'm setting the version to Inherited from OOo.
