importing google calender into Kontact

Hi,

i had another question concerning integration of google calender and Kontact. 
I am synching (one way) google calender with Kontact::calender. This works for 
the regular calender.

However, i created a calender in google::calender using the birthdays that are 
from my google::contacts. When i try to import those into Kontact::Calender i 
get nothing. There is no error message though.

So i am not sure what the problem is (i suspect it is on google's end).

Does anyone have similar issues?

thanks
matt
