But "here" (Debian 5.0 with 2.8.2dev.12 or 2.8.7rel.1) both hang.
The difference between rel.1/rel.2 is not related to this area.
Comparing traces on your working/non-working versions might show
something useful - if I trace it, I see this error:

        HTParse:      result:`sempreaovivo.radio.br'
        Looking up sempreaovivo.radio.br
        HTGetAddrInfo: getaddrinfo(sempreaovivo.radio.br, 80): Name or service 
not known
        Unable to locate remote host sempreaovivo.radio.br.
        HTTP: Unable to connect to remote host for 
`http://sempreaovivo.radio.br/' (errno = 2).

        Alert!: Unable to connect to remote host.

        HTAccess:  status=-29999
        HTAccess: `http://sempreaovivo.radio.br/' has been accessed, No data

        stop_curses: done.

fwiw, it also hangs from my desktop with firefox.
