The problems persists with skype-1.2.0.18, causing to freeze and crash
shortly after establishing a call.

Then I upgraded to the latest 1.3.0.53 and everything works like a charm.
I tested it thoroughly with a lot of calls.

Another thing is, that skype continues to run, after you close the skype window.
The only clean shut down is via File->close. This problem existed in
1.2.0.18 aswell.

And a short message should advice the user to set record.source=mic,
after skype has been installed via pkgsrc.

This PR can be closed. (as soon skype is updated to 1.3.0.53)

Zafer.
