Request Tracker 4.2.12 - Cannot create scrips

I recently inherited a RT installation, and after upgrading it to 4.2.12 scrips can no longer be created. This happens if someone is trying to create a scrip local to a specific queue or globally. The standard "An internal error has occurred" message is kicked out.

When I look in syslog, I see

[17510] Can't call method "Queue" on an undefined value at /opt/rt4/sbin/../lib/RT/Scrip.pm line 450.#012#012Stack:#012  [/opt/rt4/sbin/../lib/RT/Scrip.pm:450]#012

The offending code is in the Stage() method in Scrip.pm

 446 sub Stage {
 447     my $self = shift;
 448     my %args = ( TicketObj => undef, @_ );
 449     my $queue = $args{'TicketObj'}->Queue;
 450     my $rec = RT::ObjectScrip->new( $self->CurrentUser );
 451     $rec->LoadByCols( Scrip => $self->id, ObjectId => $queue );
 452     return $rec->Stage if $rec->id;
 453 
 454     $rec->LoadByCols( Scrip => $self->id, ObjectId => 0 );
 455     return $rec->Stage if $rec->id;
 456 
 457     return undef;
 458 }

I have verified that $args{'TicketObj'} is what is undefined. I'm a bit stumped with where to go from here. Any help is appreciated.
