Doesnt work now.
I can add app to locked list successfully but the applock fails to lock the phone when locked app is opened.

BusyBox v1.10.2 (Debian 3:1.10.2.legal-1osso30+0m5) built-in shell (ash)
Enter 'help' for a list of built-in commands.

/home/user # applock --add /usr/share/applications/hildon/dorian.desktop
Maemo applications must be run with the run-standalone.sh script!
QGtkStyle was unable to detect the current GTK+ theme.
Adding /usr/share/applications/hildon/dorian.desktop to the list of locked applications
Application Monitor Loaded:
Name: "Dorian"
Path: "/opt/maemo/usr/bin/dorian"
Name: "Dorian"
Executable: "/opt/maemo/usr/bin/dorian"
Added to list of locked apps
QSqlDatabasePrivate::removeDatabase: connection 'qt_sql_default_connection' is still in use, all queries will cease to work.

This is he output when I try locking Dorian.
