Description of problem: kdebase-workspace-libs-4.1.0-8.fc9 provides libplasma.so.2, as needed by kdeplasma-addons-4.1.0-1.fc9. The trouble is that extragear-plasma-4.0.1-5.fc9, present in an installation set, requires libplasma.so.1. Version-Release number of selected component (if applicable): kdebase-workspace-4.1.0-8.fc9
kdeaddons-plasma Obsoletes/Provides extragear-plasma, and is properly linked against the new(er) libplasma.so.2
You mean kdeplasma-addons-4.1.0-1.fc9, I guess. 'repoclosure' utility somehow managed to miss that without any apparent reason. My mistake.
repoclosure doesn't really understand Obsoletes. This is a false positive.
