When I try to access a folder trough for instance Amarok's tab (where the file is located) instead of Dolphin it opens KTorrent informing me that the file is invalid..

It might have something to do with authorising Konqueror to remember opening magnet links in Ktorrent?

Oh and it keeps appearing in tray (KTorrent) although I keep removing it..

I removed ktorrent from the inode/directory mimetype in KDE's System Settings -> File Associations, thanks to joris.guisson@gmail.com.
