Summary:                    xffm cannot browse smb shares
Description: 
xffm 4.0.2, samba 3.0.1

while trying to access the smb network xffm hangs and CPU
load raises to 100%. In the status window I can see:

Looking for master browsers ...
XFSAMBA> nmblookup -M -- -

The same setup with 4.0.1 worked fine, if I execute the 
nmblookup command on the commandline, I get the correct
master browser:

$> nmblookup -M -- -
querying __MSBROWSE__ on 192.168.0.255
192.168.0.90 __MSBROWSE__<01>

It could be that the version of samba you are using has a signal handler
attached to sigcont. Please apply this patch in reverse (or copy
libs/tubo.c) from the 4.0.1 tree to the 4.0.2 tree and confirm that
xfsamba4 works (or does not):

Yep, confirmed. xfsamba4 works if i use tubo.c from the 4.0.1 tree.

Perfect. As soon as I do some testing of samba-3.0.1 on FreeBSD I will
update CVS and close the bug. Thanks.
