The sequence below has happened twice so now i think it may be a bug, not a
personal failure.

What happens

I set IndependentBranches to "prevent" using the admin interface. Immediately
after setting the preference, everything works fine. In fact i work on koha
configuration for the rest of the day, log off and back on several times and
everything is fine. However, the next day (perhaps because the crons have run
overnight) when i try to access the intranet, i get this error.

Software error:
Can't use an undefined value as a HASH reference at
/usr/share/koha/intranet/cgi-bin/mainpage.pl line 53.
For help, please send mail to the webmaster ([no address given]), giving this
error message and the time and date of the error. 

-----------

my $branch =
  C4::Context->preference("IndependentBranches")
  && !$flags->{'superlibrarian'}
  ? C4::Context->userenv()->{'branch'}
  : undef;

-----------


I log into the server and do the following

mysql> select * from systempreferences where variable="IndependentBranches";
+---------------------+-------+---------+---------------------------------------------+-------+
| variable            | value | options | explanation                          
      | type  |
+---------------------+-------+---------+---------------------------------------------+-------+
| IndependentBranches | 1     | NULL    | If ON, increases security between
libraries | YesNo |
+---------------------+-------+---------+---------------------------------------------+-------+
1 row in set (0.00 sec)

mysql> update systempreferences set value=0 where
variable="IndependentBranches";
Query OK, 1 row affected (0.04 sec)
Rows matched: 1  Changed: 1  Warnings: 0


This fixes it, and lets me enter the intranet but strangely i enter logged in
as an OPAC user (who does not have permission to enter the intranet area). I
only have one OPAC user created by the way, and obviously was not previously
logged in as that user in the intranet but i may have been logged in as that
user in the OPAC. If i log out and try to sign in as that same OPAC user again,
it correctly gives me the message that i do not have permission to access that
page.
