That is not necessarily the users primary group, the users primary
group is the one displayed by 'getent passwd username' e.g.

root@dc4:~# getent passwd SAMDOM\\rowland
SAMDOM\rowland:*:10000:10000:Rowland Penny:/home/rowland:/bin/bash

The second number is the users primary group, in this case '10000',
which is:

root@dc4:~# getent group 10000
SAMDOM\domain users:x:10000:

But if I create a file in a share and ensure it belongs to the user
with a group that isn't the users primary group (which seems to be what
you are describing), I get:

root@dc4:~# ls -la /srv/samba/Demo/test.txt 
-rw-rwxr--+ 1 SAMDOM\rowland SAMDOM\unixgroup 0 Aug 16 11:29 /srv/samba/Demo/test.txt

And getfacl shows:

root@dc4:~# getfacl /srv/samba/Demo/test.txt 
getfacl: Removing leading '/' from absolute path names
# file: srv/samba/Demo/test.txt
# owner: SAMDOM\134rowland
# group: SAMDOM\134unixgroup
user::rw-
user:root:rw-
user:SAMDOM\134rowland:rw-
group::r--
group:SAMDOM\134unixgroup:r--
group:SAMDOM\134unix\040admins:rw-
mask::rwx
other::r--

If I now go to a Win7 machine, log in as 'rowland', open explorer and
navigate to the file, right click it, select 'Properties' ->
'Security', it opens correctly (without crashing) and displays the
owners etc.

The share in smb.conf is this:
[Demo]
       path = /srv/samba/Demo/
       read only = no

If it is crashing for you, we need to know why.
What OS ?
What version of Samba ?
What is in your smb.conf ?
What is the DC ?
