sqlite3.OperationalError: duplicate column name: Mime-Version

How is the status @simonw ?

[McPolemic]

I ran into this problem as well. It looks like Gmail outputs multiple columns that are the same name and just different capitalization. Unfortunately, SQLite column names are case-insensitive. I output the SQL command that mbox-to-sqlite was using to create the table and put it in a gist in case that ends up helping.

Same here.. I got: sqlite3.OperationalError: duplicate column name: Mime-Version

from @McPolemic's gist, it looks there are two columns which are causing the issue in my case: [MIME-Version] TEXT and [Mime-Version] TEXT
