Comment 2 for bug 1657961

I have encountered the same (or similar) problem here.

I'm running Debian Stretch, installed Xfce and LxQt, but only use LxQt desktop. At the first run, menulibre was showing all the categories and launchers, and they were all visible and accessible. I deleted some local launchers in ~/.local/share/applications (which had been accidentally created by Midori -> Bookmarks -> Create a launcher) and then I exit menulibre program. When I rerun it, all the categories were there, but they were empty - no launchers at all. My actual main menu is fine, but it's no more represented in menulibre (except the empty categories). At that point, I noticed that menulibre status line was showing "/usr/share/desktop-directories/lxde-*.directory" for actual location of -empty- menu categories. I don't know if it's of importance.

Environment: Debian Stretch, LxQt 0.11.1, menulibre 2.0.7
