squealing noise when clutch shifting on 2008 Saab 9-3

my husband has heard it on several occasion but i have not..i always preheat my car for at least 10 minutes whereas he will get in it ice cold and take off...he thinks its something with the throw bearing or something tht sounds like that...i think it does it only when car is cold...is it a problem?
