Fails to create duplicate if unwritable

[jeremypw]

What Happened?

If a file's write permission is changed during editing then the "Save Duplicate" option of the resulting dialog fails to create a new file in the selected location even though the tab is renamed.

Steps to Reproduce

• Create and open a writable text file
• Edit it with the "Save changes" option on
• Remove the write permission of the file
• Edit some more
• In the resulting dialiog press "Save Duplicate"
• Select the same (writable) folder but a different file name
• No file is created and the tab remains locked but renamed

Expected Behavior

A writable duplicate should be created in the requested location and the tab lock removed.
