Wierd LUA Errors (with no addon name)

[Dakeyras]

I'm getting 2 errors each time I log in, been like this for a while now and only now decided to try to fix it (yes, I'm lazy).
The problem is that the errors don't contain an addon name, the both say
"Error occured in: Global"
Would appreciate any help trying to decipher this.
Here are the full errors:

Thanks in advance :)

[Pharaunmizz]

So, I'm going to ASSUME that the problem isn't originating in Blizzard's code (you don't get the error without addons, right?). It could be hard to track down that specific error (THANKS FOR THE STACK TRACE, BLIZZARD!), but that's a template anyone can use.

If you can recreate it reliably (if it's a login error, then you can recreate it easily!), then do the binary search tree:

Disable half of your addons, log in, try to recreate it. If you see the problem, then you know it's in the half you've still got running.

If you don't see the problem after recreating it, then it's in the other half, so you have to re-enable that half and disable the other half.

Then, keep cutting the existing set of addons down in half until you get to a single culprit addon.

Funny outcome, updated some addons last night (always update my addons before raids), and suddenly the errors disappeared (after being there since 3.3).

I think the culprit was Mobinfo2 which was updated this week after a few months of inactivity.
