# package-cleanup --problems
 
Actual results:

Setting up yum
Reading local RPM database
Processing all local requires
Missing dependencies:
Package libtheora requires libogg.so.0
Package kdemultimedia requires libogg.so.0
Traceback (most recent call last):
  File "/usr/bin/package-cleanup", line 349, in ?
    main()

    provsomething = buildProviderList(my,pkgs,opts.problems)

    if not result.has_key(po.pkgid):

Documented behavior.
