Segfault with changing Solaris ACLs

[ed . rolison]

Hi. I think I've encountered a problem in cfengine (agent)  2.0.a14 when
setting acls on a directory.
I use (in files) the following snippets:

files:
     bbhosts::
          ${bbpath} mode=og-w owner=bigbro group=bigbro action=fixall
recurse=inf
          ${bbpath}/etc mode=og-w owner=bigbro group=bigbro acl=bbsolaris
action=fixall recurse=inf

acl:
     { bbsolaris

     method:append
     fstype:solaris
     user:erolison:rwx
     mask:*:rwx
     }

The first time I run cfagent, I get a segfault (after a few entries it
seems) leaving a cfengine_lock_db (which I need to manually clobber
in order to continue otherwise cfagent reports that it's already running.)
(In case you hadn't guessed, the purpose of these entries is to keep 'Big
Brother' configurations and versions in step, and to set certain files so I
can edit them.)

Cheers.
