strace smbclient 3.6.0

I upgraded to 3.6.0, but since that time, I can't connect to a share on a NT4 Wks host any more:

# /usr/bin/smbclient //molek-04/lightcycler -U administrator
protocol negotiation failed: NT_STATUS_IO_TIMEOUT

I thought it could be something with 'client ntlmv2 auth", what is 'yes' since that version. But even if I switch it to 'no' it's the same.

[root@nucleus ~]# smbclient --version
Version 3.6.0 

I have this problem reproducable on all our 3.6.0 machines. From none I can use smbclient to connect to NT4 shares anymore. With 3.5.x versions it's no problem.

Volker Lendecke already told me on the mailing list, that thought that he had this problem already in a 3.6pre version and it was fixed. But I'm running the 3.6.0 final here and having this problem.

Using "-p 139" as parameter is a workaround for the problem.

Volker already told me via mail that the output of poll(2) from the straces of 3.6.0 and 3.5.11 look different.

Just to say this is pretty high on my list, but I am right now very busy with
customer issues.
