BIB: I do this as well with most of my 'th's. I don't think it's to do with accents although it does seem to be more prevalent in the south of England (Ferne is from Essex, I'm from Southampton.)
I think it's more to do with not being corrected as a child and never learning the difference between the two, as they sound similar, and then not being able to shake the habit as you get older.
