Hi

I'm not sure that there was any problem in OTP.
According to the documentation (http://www.erlang.org/doc/man/httpd.html)
the configuration file must be an erlang list containing tuples {Option,
Value}.

Here is a correct configuration file:

$  cat test_ok.conf
[{port,8080},{server_name,"httpd_test"}].
$ erl
Erlang (BEAM) emulator version 5.5.5 [source] [async-threads:0] [hipe]
[kernel-poll:false]

Eshell V5.5.5  (abort with ^G)
1> file:consult("test_ok.conf").
{ok,[[{port,8080},{server_name,"httpd_test"}]]}


Reading your patch, I think that your configuration file looks like:
$  cat test_bad.conf
{port,8080}.
{server_name, "httpd_test"}.
$ erl
Erlang (BEAM) emulator version 5.5.5 [source] [async-threads:0] [hipe]
[kernel-poll:false]

Eshell V5.5.5  (abort with ^G)
1>file:consult("test_bad.conf").
{ok,[{port,8080},{server_name,"httpd_test"}]}
