[Samba] smbfs mounts cause hangs in kde/gnome

[rich lott]

I'm using debian Sarge, Samba 3.0.6-3, Kernel 2.6.8

I use smbmount //server/share mymountpt -oguest which connects fine, but it 
all dies (hangs) if I try to look in that mounted directory with konqueror in 
kde OR nautillus in gnome.

In dmesg of the server computer I get:

smb_proc_readdir_long: error=-512, breaking

and the same but with error -13

smb_add_request ... Timed Out!

this last one repeats infinitely.

and often some other stuff too. I've googled till I'm goggled and all I've 
found is similar postings but without answers.

thanks
