[rt-users] Unchecking "Let this user be granted rights" results in hang

[Peter Struijk]

Hi Carl,

This simple change, courtesy Jesse, solved the "RT hanging" issue for me. I 
don't use fastcgi. Your mileage may vary.

In ACE_Overlay.pm, find

sub Object {
my $self = shift;

my $appliesto_obj;

if ($self->__Value('ObjectType') && $OBJECT_TYPES{$self->__Value(
'ObjectType')}
) {
$appliesto_obj = $self->__Value('ObjectType')->new($self->CurrentUser);
unless (ref( $appliesto_obj) eq $self->__Value('ObjectType')) {
return undef;
}
$appliesto_obj->Load( $self->__Value('ObjectId') );
return ($appliesto_obj);
}
else {
$RT::Logger->warning( "$self -> Object called for an object "
. "of an unknown type:"
. $self->ObjectType );
return (undef);
}
}


remove:

$RT::Logger->warning( "$self -> Object called for an object "
. "of an unknown type:"
. $self->ObjectType );
