1. Add or update a .gitignore file
2. Rebase your repo such that the .gitignore from step one is positioned in history prior to the naughty file(s) being commited.
3. Run this command, where <commit> is the hash for the commit respresented by step 1: git rebase -ix 'git rm -r --cache . && git add . && git commit --amend --no-edit' <commit>
4. Resolve conflicts as necessary.

Note that if there are only a few file types or directories or individual files, filter-branch is a simpler route to take. These steps are only necessary for large numbers of files / file types. Also note that there may be better ways still of doing this. :-)
