I recall there was another method. Yeah, I even found it (using ghci and set -fbreak-on-exception)

Careful, better use -fbreak-on-error rather than -fbreak-on-exception. Some functions, e.g. 'doesFileExist', use exceptions internally and you might end up stopping at an exception that is benign. (Identifying the exception has become a little harder since we got extensible exceptions.) -- Push the envelope. Watch it bend.
