This is a duplicate of bug 169103 :)
Darío is right, it is a duplicate. The bug is fixed in KDE 4.1.3. If you can't upgrade now, you can solve your problem in the meantime by deleting the Dolphin configuration, probably located at ~/.kde/share/config/dolphinrc or ~/.kde4/... *** This bug has been marked as a duplicate of bug 169103 ***
