Comment 4 for bug 719983

After investigation it turns out that the BamfApplication's user_visible property is set to false for some KDE3 applications such as Kommander Editor (package kommander-kde3) which means that the launcher is not going to display it. See line 232 of libunity-2d-private/Unity2d/launcherapplicationslist.cpp:

    if (!bamf_application->user_visible()) {
        return;
    }

It seems that the property user_visible is set to true very quickly after the signal ViewOpened is emitted but it's already too late.
