Fedora 16 has an unfinished transaction?

I was doing an update in Fedora 16, but the process isn't complete and throw me a weird message.

There are unfinished transactions remaining. Please run yum-complete-transaction as root.

Not sure what is happening, just follow the given instruction and there is a bunch of nonsense as shown below is thrown to me. After this command execution, everything went normal. What a fun?!!
