Bug 378050 (auth_smbc_get_data)

I'm running KDE Platform Version 4.14.10, and all components (dolphin, konqueror, etc) cannot use SMB.

Turning on the kdebug for kio_smb gives me the following when I type "smb://guest@192.168.6.20/core/" into any URL bar:

kio_smb(21703) SMBSlave::auth_initialize_smbc: auth_initialize_smbc
kio_smb(21703) SMBSlave::auth_initialize_smbc: smbc_init call
kio_smb(21703) SMBSlave::stat: KUrl("smb://guest@192.168.6.20/core/")
kio_smb(21703) SMBSlave::checkURL: checkURL  KUrl("smb://guest@192.168.6.20/core/")
kio_smb(21703) SMBSlave::checkURL: checkURL return3  KUrl("smb://guest@192.168.6.20/core/")
kio_smb(21703) SMBUrl::updateCache: updateCache  "/core/"
kio_smb(21703) SMBSlave::auth_smbc_get_data: AAAAAAAAAAAAAA auth_smbc_get_dat: set user= guest , workgroup= WORKGROUP  server= 192.168.6.20 , share= core
kio_smb(21703) SMBSlave::auth_smbc_get_data: libsmb-auth-callback URL: KUrl("smb://192.168.6.20/core")

and there it will hang.  If I try again, it'll just replicate those lines.  

tcpdump shows nmb name queries for core, and then a TCP three-way handshake to the correct server, and then eventually a TCP teardown with FIN, etc.  No data is exchanged on the connection.

From the code, the next step is to check the password, but I can't figure out where it's hanging before that.
