I have tried this on my lab device and it seems your right. with new chrome 21.xx version we are seeing this error for gmail, you tube and other google sites. and google uses spdy for theese websites so that it can streamline all the https requests in one tcp connection and turning off this spdy feature did fix the issue. However I was not able to figure out why these settings effect the ssl decryption. Packet captures show some RST's.
