** Description changed: [ Impact ] Malcontent is a parental control mechanism implemented in GNOME Shell. It supports hiding applications from the application menu. Some desktop snaps like telegram-desktop are no longer visible in GNOME Shell when libmalcontent is installed, even without any filters applied. Which snaps are hidden depends on the numbers of command-line arguments they specify in the Exec line. If it's more than 2, then the snap will be hidden. For example, telegram-desktop uses: Exec=/snap/bin/telegram-desktop -- %U Ubuntu ships a patch in malcontent to allow filtering non-flatpak applications too. This patch assumed that a desktop snap Exec= line would always follow the format `Exec=env BAMF_DESKTOP_FILE_HINT=foo.desktop /snap/bin/foo arg1 arg2`, so it would interpret the third argument as the absolute binary path. That was changed in snapd version 2.72 to remove the BAMF_DESKTOP_FILE_HINT environment variable, so the Exec line now follows the format `Exec=/snap/bin/foo arg1 arg2`. The third argument is no longer the binary's absolute path, and things break. Malcontent needs to be adapted to not assume that the snap binary is always the third argument. [ Test Plan ] - 0.
