m_nepomukWatcher = new QDBusServiceWatcher("org.kde.NepomukServer", 
QDBusConnection::sessionBus(), QDBusServiceWatcher::WatchForOwnerChange, 
this);

that should get you a watcher that only triggers when org.kde.NepomukServer 
comes or goes. efficient (the filtering is done on the dbus server side) and 
easy :)

the latter sounds good to me; the user of KActivityIcon probably doesn't care 
particularly why the icon has changed, right?

sounds good.

if there are no use cases for it, then imho no.

imho, no.

imho, no.
