Double entry for Skype in Software Center not seen in Synaptic

[lunix]

I am noticing that the Software Center has two entries on my system for Skype.
They are both identical although different wording. Mine says:
Skype (followed by stars (502))
skype (Notice the lowercase 's' in Skype.

Then below is another instance that reads:
Skype (followed by stars (502))
Skype Internet Telephony

Both are shown as installed although only one Skype has been installed.

Skype claims this is a bug in the SoftWare Center but so far I can't figure out where the entries really are
and what to do about.

If I delete one of these then Skype is gone and I am convinced by clicking on "More Info"
that they are the same version of SKype.

Now what I have determined is that this only happens when Ubuntu 12.04 was not freshly installed
but was done via the upgrade method over the Internet. If one does a fresh install then the
Software Center does not have the duplication.

Does anyone else see this or have an idea how I can clean it up?

I would prefer to get responses from people who have also seen this and have found a solution
rather than rampant speculation.

I can send a screen shot to anyone requesting directly to their email account.
