Bad file association for gnome shortcuts
Note to myself :
Recently I upgraded my desktop to Ubuntu Natty at $WORK. Some file associations broke, ok. It wasn’t a problem til the moment I tried to open a shared samba device in gnome menu’s shortcuts, and chose the wrong binary to open that. From now, every time I tried to open a shortcut in this menu, LibreOffice was launched, argl :(
The place where this setting was saved has been pretty hard to find, but I finally identified it in
$HOME/.local/share/xfce4/helpers/custom-FileManager.desktop. Just removed this file and everything’s ok now.
