Description of problem: The file /etc/cron.daily/packagekit-background.cron doesn't have the execute permissions, so cron will refuse to run it (run-parts will check "if [ -x $i ]; then"). Version-Release number of selected component (if applicable): PackageKit-cron-0.1.12-13.20080522.fc9.i386 Easy fix: the mentioned file should get the same access rights as the other files in the cron.daily directory: 755.
Fixed upstream in commit b9dc48deafe36c69457ed5bfab697db51e75bbf4, many thanks for reporting this. Richard.
