Protocol Violation with Google IPs

Hello Guys,

                   Anyone is having ProtocolViolation alarms with Google IPs? Analizying the packet trace I've noticed that either GMAIL or Google Talk is alerting Protocol Violation for the HTTP Analyzer.

t=1201268671.707425 no=ProtocolViolation na=NOTICE_ALARM_ALWAYS sa=x.x.x.x sp=1233/tcp da= dp=80/tcp msg=x.x.x.x/1233\ >\\ analyzer\ HTTP\ disabled\ due\ to\ protocol\ violation sub=not\ a\ http\ reply\ line tag=@4792


I can look into it if you send me the trace (just the single
connection reported in the alarm please).
