samba - Aug 2003 - smbd crash on character conversion

Hi all,

I'm trying to share a directory that contains files with non-ASCII
characters (actually, hungarian chars, iso8859-2 or utf8 encoding, I'm not
sure - the encoding of ext2) in their name. When I mount the share and try
to list the contents of the directory, smbd crashes.

samba version: 3.0.0rc1

The shared dir is on an ext2 partition. My system is a debian woody. iconv
is installed and samba's configure script founds it, however, it seems
that smbd uses its own smb_iconv().

In smb.conf I tried the parameter "character set = iso8859-2" and
other
values as utf8, cp852 etc, but the crash persists.

log.smbd is below. Thanks in advance for any hints.

Regards,
Tibor

I've been doing a *lot* of work on this since RC1. Please test
with RC2 (due very soon) and log a bug if you can reproduce
this problem with RC2.

Thanks,
