Okay I ran the combo update. It seemed okay for one day and then the pop-ups from sys preferences for the gmail accounts started up again. This morning, mail had crashed when I awoke the Mac and I also saw all of the warning pop-up flags from preferences along the notification pane. Not sure if that issue with gmail accounts is what is crashing mail all of the time. My Mac seems to run better over all after the combo update: I was also having issues with iTunes pausing playback all of the time after that previous update. I was also experiencing sluggish performance overall before the combo update (memory, spinning wheel) and I have a very beefed up machine here.
What I did after restarting Mail today is I deleted ALL of my gmail accounts (since they are IMAP anyways). I re-setup only two of them in Mail. Then i checked Mail preferences and see that for incoming and outgoing server info, Mail did NOT fill-out the password and for the user name it left off "@gmail.com" -- any idea if that is required?
I'll test it today to see if this clears up the issues I was having.
