I receive this when right-clicking a user name and trying to use the Send Tell option. It happens if I right click in chat or anywhere in the social window (/who pane, guild pane, etc.)
It's been happening for at least 2 weeks now. I was hoping whatever mod was responsible would be updated, but apprently it hasnt been ;)
Here's a list of my current installed mods. Please note, a lot are disabled.
Iteratively enable/disable your addons until you figure out which one is causing it. I can almost guarantee noone is going to figure this out for you without you taking some action on your own. Start disabling half your addons at a time, when it goes away, reenable and then disable half of those and so on until all you're left with is the offending addon.
