You might find it easier to solve this using itertools.groupby.

def get_text_blocks(filename):
    import itertools
    with open(filename,'r') as f:
        groups = itertools.groupby(f, lambda line:line.startswith('-- -'))
        return [''.join(lines) for is_separator, lines in groups if not is_separator]

Another alternative is to use a regular expression to match the separators:

def get_text_blocks(filename):
    import re
    seperator = re.compile('^-- -.*', re.M)
    with open(filename,'r') as f:
        return re.split(seperator, f.read())
