Description of problem: kdiff3 will not compare two Fedora 9 ISO images Version-Release number of selected component (if applicable): How reproducible: download Fedora 9 iso image for installation copy/backup to a DVD (the files were written like ordinary files for backup) copy the file (Fedora 9 iso image for installation) from the DVD to a directory in the /root directory compare the downloaded file to the file read from the DVD see attached snapshot for crash in kdiff3 I suppose the Fedora 9 iso image for installation is some kind of different file. This was an attempt to verify the backup of the files used to burn the install DVD (that worked perfectly) A problem in k3b hinders this verification since an error is reported when the iso burn is verified. kdiff3 DID work to at least compare the 4 different installed DVDs Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
Created attachment 305568 [details] snapshot of the kdiff3 crash
copy/backup to a DVD (the files were written like ordinary files for backup) corrected to copy/backup to a DVD (the file was written like an ordinary file for backup)
regular old diff did work!

Please report this to kdiff3 upstream. I wouldn't really have expected to use kdiff3 to compare binary files. It wouldn't be useful even if it didn't crash. What would you expect it to do that you couldn't do with a non-gui tool such as cmp?
how would anybody know what anything does with the state of documentation the way it is! I would never complain but since you asked! I thought kdiff3 was a gui version of diff that as I stated worked! Everybody lives in their own little world where everybody is familiar with a few things and the rest of the world must presume! Making "good" presumptions is the way successful Linux users are successful! Take k3b! Reading/writing CDs/DVDs is a career unto itself! I was lucky (?) to have produced 4 working F9 installations DVDs. No wonder many neophytes give up and return to Bill! Turns out (see other bugs) there is no way to verify the install DVD is correct! Why? Burning the ISO image with verify always gets an error! I did make 4 install DVDs and using kdiff3 compared all 4. Unlikely all 4 are bad! I am surprised there is any controversy about why anybody would maintain a dual boot system! I don't like MS!
