Someone has created another bug report Bug 359850 but with a temporary work around. i'll mark this as duplicate. Work around:- If you go to file associations -> inode -> directory change the order to use dolphin. Then in Default application Dolphin is checked and place in first position. Look like the default application had becomed a viewer of file association. *** This bug has been marked as a duplicate of bug 359850 ***
