RoundCube Webmail and encoding

["Joel CARNAT" <joel%carnat.net@localhost>]

Hello,

I've just installed roundcube (on NetBSD 4.0).
It seems it can't display emails that are not UTF-8 encoded.
And even for those email, some parts (like From, To ...) are not displayed.

Did I miss some packages or did I forget to configure something ?

The package was compiled with:
These options are currently enabled:
        gd iconv ldap mcrypt multibyte mysql sockets

And the packages version are:
php-5.2.5nb1
php5-eaccelerator-5.2.5.0.9.5.2
php5-mysql-5.2.5
php5-gd-5.2.5
php5-iconv-5.2.5
php5-pear-1.5.4nb1
php5-pear-MDB2-2.4.1
php5-pear-Net_Socket-1.0.8
php5-pear-Net_SMTP-1.3.0
php5-pear-Mail_Mime-1.4.0
php5-pear-Auth_SASL-1.0.2
php5-pear-MDB2_Driver_mysql-1.4.1
php5-ldap-5.2.6
php5-mbstring-5.2.6
php5-mcrypt-5.2.6
php5-sockets-5.2.6
roundcube-0.1.1

I found a similar error here : http://trac.roundcube.net/ticket/1484023
So I tried running roundcubemail-trunk-r1342-20080429.tgz but it's still
the same.

any thoughts ?
TIA,
  Jo
