Is there any way you can try a later version of Samba ? I ask this 
because trans2.c has been replaced by smb1_trans2.c and smb2_trans2.c in 
later versions (the portion of code you are referring to is in 
smb2_trans2.c now).

I would also like to point out that sharing an NFS share with Samba, has 
never been a good idea.
