[Bluez-devel] hcid dies on socket connect attempt.

On a Fedora Core 4 system we have:

dbus-0.33-3
bluez-utils-2.15-7
bluez-libs-2.15-1

hcid starts up fine:

==============================================================================
hcid -n
hcid[12537]: Bluetooth HCI daemon
hcid[12537]: Starting security manager 0
==============================================================================

As soon as I try to get a Bluetooth connection, however, it dies (see
below).
What might be wrong?

This code works well on Fedora Core 3. Has something changed? We establish the
connection as follows:

int connection;
connection = socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);

struct sockaddr_rc local;
local.rc_family = AF_BLUETOOTH;
local.rc_channel = 0;
bacpy(&local.rc_bdaddr, BDADDR_ANY);
bind(connection, (struct sockaddr *)&local, sizeof(local));

struct sockaddr_rc remote;
remote.rc_family = AF_BLUETOOTH;
remote.rc_channel = /* supplied channel number */;
bacpy(&remote.rc_bdaddr, &/* supplied addreess */);
connect(connection, (struct sockaddr *)&remote, sizeof(remote));

Now here's now hcid dies:

==============================================================================
hcid[12537]: link_key_request (sba=00:0A:3A:53:D7:FC, dba=00:A0:96:0A:C9:10)
hcid[12537]: pin_code_request (sba=00:0A:3A:53:D7:FC, dba=00:A0:96:0A:C9:10)
12537: arguments to dbus_type_is_basic() were incorrect, assertion
"_dbus_type_is_valid (typecode) || typecode == DBUS_TYPE_INVALID" failed in
file dbus-signature.c line 259.
This is normally a bug in some application using the D-BUS library.
type unknown isn't supported yet in dbus_message_append_args_valist
