Subject: obexd-0.8 get OBEX_HDR_NAME NULL

hi, all :

I'm using obexd-0.8 and openobex-1.5 on my pxa310 platform.
and I want to send files from a mobile phone to the platform.

but, when i start receive-file agent, it exit quickly, and no files have
been received !
I found that: in obexd-0.8/src/obex.c, line 644, func: check_put, there
is:

os->name = g_convert((const gchar *) hd.bs, hlen,
"UTF8", "UTF16BE", NULL, NULL, NULL);
debug("OBEX_HDR_NAME: %s", os->name);

on my platform, hlen is correct, but hd.bs is empty. so get os->name is
NULL.
then, in obexd-0.8/src/obex.c, line 688, it is failure, and returned.

if (!os->name) {
OBEX_ObjectSetRsp(obj, OBEX_RSP_BAD_REQUEST,
OBEX_RSP_BAD_REQUEST);
g_free(os->type);
os->type = NULL;
return FALSE;
}

How to fix it ? why the hd.bs is empty ?
Thanks in advance for any helps.

Best regards
yesir Yao.

I have found that the function "g_convert" returns NULL. It shows error
as "Conversion from character set 'UTF16BE' to ' UTF8' is not supported.
"

I have installed glib-2.18.3 on my platform, but have not installed
libiconv on my platform.

is it the reason i failured ?
Thanks in advance for any helps.
