Maybe 2 out of 5 times, when I attempt to log out or exit the game, WoW crashes with the following message:

ERROR #132 (0x85100084) Fatal exception!

I do not believe this is a hardware issue, because it happens on two different computers, my desktop and my boyfriend's laptop. It has happened under Win7 Ultimate (64-bit), Win7 Home Premium (64-bit), and WinXP Professional (64-bit). It happens with both the 32-bit WoW client and the 64-bit one. My desktop has gotten a new motherboard, CPU, RAM, SSD, fresh install of Windows, and fresh install of WoW since the problem began occurring (though this problem was not the motivation for the hardware upgrades ). Also, I've noticed that if I reload the UI immediately before logging out or exiting, this never happens. For these reasons, I believe the issue is being caused by an addon.

However, because this doesn't happen 100% of the time, and it seems to take about 5 minutes after logging or reloading the UI before it can happen, I haven't felt like spending my whole weekend trying to identify which of my 100+ addons is causing it yet.

Has anyone had, or heard of, a similar problem, or have any suggestions for types of addons that may be able to cause such a problem? I'm mainly looking for any tips on quicker ways to narrow it down than having to be logged in for 5+ minutes between logging out and enabling/disabling some more addons.

I can post detailed crash logs and/or system specs if someone wants them.

Edit:
Here is a list of my addons. I omitted the ones that I've installed very recently for brevity, since the problem has been going on since at least December. I included a brief description next to my private addons.

!!AceDBMod - copy of AceDB-3.0 modified to default to Default profile instead of per-character, with minor version set to 99999 so it overrides all the embedded copies in my other addons
!!Sandbox - miscellaneous testing things, mostly API tests that simply print messages when events/functions happen
