taintLog 1 causing crash to desktop or error

Bug Report
The game can crash to the windows desktop or display a Lua error when the taintLog setting is 1. Neither occurs when the taintLog setting is 0. This is on the live server after 5.0.4.

The following thread on wowinterface.com discusses a Lua error that can occur and provides a basic test addon to help reproduce it.

The test addon consists of the following code:
Minimap:SetScript("OnMouseUp", function(self, btn)
if btn == "RightButton" then
ToggleDropDownMenu(1, nil, MiniMapTrackingDropDown, "Minimap", 0, 0)

My steps:
1. Enable only the test addon
2. Created new Alliance human priest.
3. Enter the world, and press ESC to skip the movie.
4. Type: /console taintLog 1
5. Type: /reload
6. Right click on minimap to show the menu.
7. While the menu is open, press M to open the map.
8. At this point it either crashes to desktop, or I get a Lua error.

When taintLog is set to 0, there is no error or crash when the same steps are performed.

The following is a copy of the Lua error that can occur:

The following is from the start of the error report that I submitted via the error reporting tool that ran when the game crashed to the desktop:

I was going to post, but a search found this - not meaning to necro it, but is this fixed or is taint still an issue?
Blizz, is this a known issue? OR do I need to keep reporting it?
This is still definitely a problem. Turning off the taint log fixes the problem, but there's no way I'd have figured that out without a search.
Was causing some very weird and random crashes in BankItems. Glad I found this thread. This was supposedly fixed during Beta, but clearly it's still broken.
Thank you for this post, this bug was driving me crazy (With or without addons).
I was afraid of pressing my "M" key to open the map.

I hope that the "/console taintlog 0" fix this madness.

If i dont update then im not getting more lua error and crashes while opening my map.

BTW the problem started with MoP. No problem before the update.
