Got this from Mint 15 RC feedback.
When an app places itself in multiple categories, mintmenu shows it more than once in search results and in "All applications".
This is the case for LibreOffice Draw for instance.
Why this has been closed? It's still reproducible in Mint 16 RC (mintMenu 5.4.9).
At the first menu invocation, gnome-disks is listed twice in "All applications". The same happens with LibreOffice Draw, of course. After switching to Favorites and back again, the duplicate goes away (you may have to click "All" after switching back).
