Description of problem: Cannot open 7z archives. arK is the KDE supplied graphical front end to read archive files, File Roller is used for GNOME. Installed kio_p7zip-0.3.1-7.fc9.x86_64 p7zip-plugins-4.51-4.fc0.x86_64 p7zip-4.51-4.fc0.x86_64 After application, was able to open 7z archives with FileRoller, but unable to open with arK. Version-Release number of selected component (if applicable): kdeutils-4.0.3-4.fc9.x86_64 kio_p7zip-0.3.1-7.fc9.x86_64 p7zip-plugins-4.51-4.fc0.x86_64 p7zip-4.51-4.fc0.x86_64 How reproducible: Try to open 7z archive with arK Steps to Reproduce: 1. Launch arK application 2. Select open, 7z does not appear as supported filetype 3. Actual results: 7z does not appear as supported filetype archive does not open Expected results: 7z appears as supported filetype archive can be opened Additional info: After installation of the 7z rpms listed above, archives are now supported using fileroller, but should be able to open using arK
7z support was simply never ported to the new plugin-based version of Ark in KDE 4. :-(
As Kevin noted, you should probably file a wishlist upstream, there's nothing we can do about this as the feature is simply not implemented
