Hi Rafael,

kio_uiserver startup shows:
Object::connect: No such slot QListView::rowsRemoved(QModelIndex,int,int)
Object::connect:  (receiver name: 'progresslist')

and apps that use kio (like kde-cp) show:
Object::connect: No such slot Observer::slotSpeed(KIO::Job*,ulong)
Object::connect: No such slot Observer::slotTotalFiles(KIO::Job*,ulong)
Object::connect: No such slot Observer::slotTotalDirs(KIO::Job*,ulong)

Please double-check those signal/slot connections.

David.
