Basics Tab Titles are not applied when viewing node

The node type Basic Tab Title is correctly reported in the node 'Edit' tab.
When I go to node 'View' instead I always see the default Basic Tab Title 'Basics'.

I think the error is in .module file line 177 where the $node_type variable is not initialized:

$title = t(variable_get('cck_fieldset_tabs_residual_title_' . $node_type, variable_get('cck_fieldset_tabs_residual_title', t('Basics'))));

by replacing '$node_type' with '$node->type' the issue should be fixed (at least it seems on my local copy).
