As part of the big bug review for 16.04 LTS I have tested this on 15.10 and the bug is still there.
The busy cursor occurs when a second instance of a LibreOffice application is opened. If Quickstarter is enabled (In LibreOffice, go to Tools -> Options -> LibreOffice -> Memory -> and check "enable systray Quickstarter"), it occurs when opening the first instance of a LibreOffice app.
