Are you sure you aren't doing anything with the ftp object in the
"more code follows"?
You are probably creating another error of the same type while
processing your exception, so the second one doesn't get caught.

like this (except with ftp obviously):
try:
    f = open('in.txt')
except IOError:
    y = open('log.txt', 'w')
    y.write('failed!')
    y.close()
