I fixed the devil. I finally found the answer at http://users.pandora.be/Ice9/Linux%20stuff/Linux_tips.html ...which is a Debian site, but Google led me there and found the answer. Here it is... --------------------------------------------------------------------- KDE returns "Couldn't find MIME type application/octet-stream" at startup and/or Konqueror returns the same error message when launching whatever application. Start the Control Center and open KDE Components/File Associations, you will see something like this Expand "application", you will probably see that there's no entry for "octet-stream". Click on "Add...", for "Group" select "application" and for "Type Name" fill in "octet-stream". This should fix it. Alternatively, I also read that you could delete the file /home/userID/.kde/share/mimelnk/application/octet-stream.desktop I tried it and it also works but I'm not too comfortable deleting files without really knowing what they do, so if you decide to do this it will be at your own risk. ---------------------------------------------------------------------- The first bit did the trick. I dunno if it was me or FC6, as I restored my FC5 root directory. I know... dumb. But, this has been the only major screwup in the pantry, so all's well that ends well. Ric
