Inconsistent Error with Conflicting Addons

[Maelynn]

Since about a week or so I'm having this really annoying error that prevents Consolid8 to print the loot messages in chat. It only happens once, when I first loot an item (looting only cash doesn't produce the error), and then the error doesn't appear anymore but the loot isn't printed at all. I pasted the error down below, at the end of my post.

At first I thought the error lies with Consolid8, but it seems that's not the case. Then I thought it was Stubby's fault (part of Auctioneer), as that's the place where the error occured according to the error message, but that also doesn't seem to be true.
I did a few tests, but now I'm hopelessly confused by the results. Here's what I've tried so far.

- reinstalling Consolid8 after removing the folder and all related files in WTF
- reinstalling Auctioneer after removing the folder and all related files in WTF
- resetting chat settings, no visible change
- trying out alts

And then a weird thing showed: on my 18 Mage I have no such error at all. I (un)checked a few addons to match the list of one of the chars that does get the error (my 42 Paladin), but I still didn't get any error. Not even when I enabled every single addon on my Mage; it all works as intended.
Then I tried it the other way around by (un)checking addons on my 42 Paladin to match the Mage's original list, but strangely enough she still gets the error. This really makes me wonder where the problem could lie, as I have 2 chars with the same addon list but with different results. It doesn't make sense. Why do only some of my chars have this error, and not all? And how come I get different results when I try to reproduce the error on alts?

Because of this weird result I also didn't bother disabling addons and checking for this error further, as it seems to me that it's rather futile if the Mage doesn't even have the error with the entire list of addons running.

Can anyone give a bit of insight on this issue? I'm stumped. And getting more and more annoyed.
