Exploring further i noted the following that could be the reason why its so broken now :
- an accenctuated character in a filename badly impacts drawers (déjàvu, bientôt...).
So i renamed all filenames so as to have no accenctuated characters : behaviour was improved.
- underscores in a filename are displayed in the menu shortlink as are usually displayed keyboard shortcuts in menus ("no_more" is displayed as "no<u>m</u>ore"). When there are many underscores in a filename, none of them appear in the menu, but only the last one is changed into a keyboard shortcut)
