Thanks for the debug, here is the useful part I think: debug : (/build/buildd/cairo-dock-3.3.2/src/gldit/cairo-dock-keyfile-utilities.c:cairo_dock_open_key_file:34) while trying to load /home/frank/.config/cairo-dock/current_theme/launchers/01freemind.desktop : Permission denied gldi_user_icon_new: assertion 'pKeyFile != NULL' failed warning : (/build/buildd/cairo-dock-3.3.2/src/gldit/cairo-dock-user-icon-manager.c:gldi_user_icons_new_from_directory:133) Unable to load a valid icon from '/home/frank/.config/cairo-dock/current_theme/launchers/01freemind.desktop'; the file is either unreadable, unvalid or does not correspond to any installed program, and will be deleted so, there is an invalid .desktop file in the launchers folder, and the dock sees it and tries to remove this invalid file. For some reason, it deletes ... the next one ! which is precisely libreoffice-impress.desktop. so, I think it's clear now and should be easy to fix. thanks again for your help :-) 2014-05-15 0:16 GMT+02:00 Frank Claessen
