Skype, Delete History?

[Qqmike]

Kubuntu 12.04, Skype 4.1.0.20:
Is there a way to delete [all] history? (e.g., chat history)

(I notice in Windows Desktop Skype, Tool > Options > Privacy --> Delete History; but I can't seem to figure out how to clear-out, clean out, my Skype past events/chat in Skype.)

For Linux, the only thing I can see to do is
Options > Privacy > Keep Chat History For = Disable History,
log out, log back in, reset Keep Chat History (for 2 weeks, etc.).

The chat conversations (and call times, etc.) seem to be cleared out that way, but the list of people you've chatted with still appears under Recent Chats.
