Magic symbol :CHE in delivery

Hello lispworkers,

I have bumped into an unexplainable error while delivering on level 5
in LWW 4.4.6. The simplified problem description is as follows.

This list is embedded into my delivered application.
(defparameter *regions*
(list (make-instance 'region :code :MOS :name "Moscow")
       (make-instance 'region :code :CHE :name "Chelyabinsk")
       (make-instance 'region :code :YAR :name "Yaroslavl")))

My application deals with standard-object instances, which refer to the
regions by code keywords. Namely, it
- creates objects,
- saves these objects into data files calling hcl:dump-forms-to-file,
- it reloads them calling sys:load-data-file.

Internally, the application retrieves regions like this:
  (find (region-code object) *regions* :key #'code)

All the regions work fine except for the :CHE region.
The above call returns NIL when delivered on level 5.
When delivered on level 4, it returns the right thing, something like
   #<REGION :CHE "Chelyabinsk">

Specifying argument
  :keep-symbol-names '(:che)
to the delivery function does not help.
