samba - Jan 2003 - libsmbclient::smbc_getdents->lotta unknown type entries..

Hi,
installed libsmbclient 2.2.3a-12 at debian 2.4.20, get great percentage of 
entries of unknown type, smbc_dirent.sbmc_type is not in range 1-9...
e.g:

<....>
WORKGROUP --> WORKGROUP
XXX --> WORKGROUP
^666^ --> WORKGROUP
 --> UNKNOWN
 --> UNKNOWN
 --> UNKNOWN
 --> UNKNOWN <-- unknown when not in 1-9 range
<....>

master browser of the group is samba 2.2.3a-6

any ideas ?
