Crashing more often now with crash-fix builds

I very infrequently crashed since EA launch, but it seems like that the more crash fixes added, the more often I'm crashing.

The most common current crash occurs after launching the game and signing in with a character, for the first time after my PC has slept. I'm noticing it primarily with my Warrior, but it could be that I'm just playing him more right now. So far I haven't had a second crash after relaunching the game and trying again. Perhaps something is being cached that ends up stale/null and the attempt to reuse it leads to a crash?

And the game decided to make me a liar this morning. Crashed 3 times in a row attempting to sign into my Warrior. Picked the Monk and successfully signed in. Logged right back out and tried the Warrior again, and that too was successful. This could still be coincidental, I'm a magnet for race conditions.
