If "Load LibreOffice during system start-up" option is not marked, exiting from any component of "LibreOffice" generates the following error message from Windows: "The instruction at "0x067d6546" referenced memory at "0x00000004". The memory could not be "read". Click on OK to terminate the program. OK button.
QuickStarter is a red herring here; The "QuickStarter" is simply having the LibreOffice process, soffice.bin, running continuously. So this is a duplicate of bug #36301.
