I saw the following behavior this evening.
It gave me quite a start, until I tried 'rpm --rebuilddb'
which fixed it.
# rpm -e djava-resolver-client djava-mailcom
package djava-resolver-client is not installed
removing these packages would break dependencies:
djava-mailcom is needed by
# rpm -e djava-resolver-client-1.3-1
package djava-resolver-client-1.3-1 is not installed
# rpm -qa | egrep 'djava-resolver'
# rpm -qa | egrep 'djava-mailcom'
# rpm --version
RPM version 2.5.6
