Tynd:
It looks like the callstack is messed up, but from reading the stack scan, my best guess would be that you have a custom Inventory window (could be replacement for the inventory window or another window called 'inventory') that doesn't have overflow text (if you're a UI modder, that's "GeneralPage.Overflow Text"). That character has items in overflow apparently.
My suggestion would be to use the default UI, log the character in and remove the items from overflow, and then go back to using your custom UI. Or you could fix the custom UI by adding overflow text
I've made a code change, but it probably won't go out until the next game update.
I don't even see the code... all I see are blond, brunette, redhead...
