What version of the product are you using? On what operating system?
v0.7.2

Please provide any additional information below.
The regular expression _re = re.compile("\033\[[0-9;]*m") doesn't match the 
xterm escape sequence for reset:

$ TERM=xterm tput sgr0 | od -xa
0000000    281b    1b42    6d5b
        esc   (   B esc   [   m
0000006

It can be fixed by tweaking the regexp a little:
_re = re.compile("\033(\[[0-9;]*m|\(B)")

rxvt and screen are affected in the same way:

$ for TERM in rxvt screen screen-256color; do echo -n $TERM:\ ; tput sgr0 | cat 
-A; echo; done | sortrxvt: ^[[m^O
screen-256color: ^[[m^O
screen: ^[[m^O

Using a regex like
  _re = re.compile("\033(\[[0-9;]*m\017?|\(B)")
fixes these as well.
