Problem calling through skype

[Yuri]

Beginning from some recent ports update (? maybe) I get a problem making 
voice calls with Skype.
Symptoms are:
All calls disconnect after exactly one minute.
Time counter on top of the window runs slow. Like one second per 7 real 
seconds.

Version is 2.0.0.72 but it used to work ok for a long time so it doesn't 
seem to be related to version.
It's either something with update of other packages, or some change in 
protocol not well taken by linux skype run on freebsd.

Anyone sees similar problem?
