Comment 26 for bug 1661590

@simosx: I gave this another test on a clean xenial VM with the same gnome-software version as you. Each time it launched the main "libreoffice" command (showing a window asking to open recent files or create a new document in one of the libreoffice applications).

gnome-software continues running when you close the window, so is it possible you were still running the old version when you saw the failure?
