Problem inserting data into 7.4.2 table

I have just upgraded to 7.4.2 from 7.2.1 and I am having problems
inserting data into a database table that worked just fine under 7.2.1.

I have a table defined as follows:

create table vm_mailbox
(
MailboxId varchar(64) not null,
MailboxType integer not null default 0,
Description varchar(64) ,
MailboxSize integer ,
MessageSize integer ,
Tutorial boolean not null default true,
TotalMessageTime integer ,
MessageExpiryTime integer ,
Enabled boolean not null default true,
GreetingType integer not null default 10,
OrphanedTime bigint not null default 0,
LastAccessed bigint ,
ZeroOutNumber varchar(32) ,
primary key (MailboxId)
);

When I try to do the following insert into the table

insert into vm_mailbox
values('PERSONAL00000000000000000000000',0,null,10000,60,true,0,30,true,
10,0,1081462504500);

I get the following error:

ERROR:  integer out of range

What is the problem? Is it complaining about the value for LastAccessed?
According to the 7.2 User Guide a bigint can have a value between
-92223372036854775808 and 92223372036854775807.
