Can you reproduce this problem with TBag as the only addon loaded?
Having TBag as the only addon enabled still produces the error

Can you reproduce this problem after renaming your stored variables file?
(WTF\Account\USERNAME\SavedVariables\TBag.lua under your WoW install, log
out of WoW, rename the file something else and log back in)

It still produces the error

Please provide any additional information below.
