I am getting this complete freeze as well, after a fresh log in. It seems to be happening in conjunction with the latest Bagnon enabled, from what I can tell. After I got the crash a few times, I removed all addons from my addons folder and then added them back in, one at a time. It was only when I added Bagnon back in that I encountered the freezing issue. In addition, I've noticed that if both TSM and Bagnon are present in the AddOns folder, TSM doesn't show up in the list of addons you can access from the character menu.
Most of the time it causes a complete freeze, but I logged back in again to make sure and it threw an LUA error after freezing for maybe 3 seconds. Caught by Swatter about 15 minutes ago.
