Take a .doc file created by Word or LibreOffice. Rename it to have the .rtf extension instead. Open if in LibreOffice. The document will be called "Untitled 1" as LibreOffice for some reason thinks the file is of a template type.
Seems to be present in 6.0, 6.1 and master at least.
Steps to Reproduce:
The document should be opened normally and be associated to the actual file name from which it was loaded.
User Profile Reset: No
This must be for the same reason as bug 110987. I had a simple fix for that, but it caused a regression: bug 119530.
