semanticdb typecache error

Hi,

Culprit file has declaration:
typedef PRInt64 PRTime;

When semanticdb file is freshly created:
("PRTime" type
                (:typedef ("PRInt64" type (:type "class") nil nil)
                 :type "typedef")
                 nil [3439 3462])

After some time it is transformed into:
((((0) (0) "PRTime")) type (:superclasses ("PRInt64" type (:type 
"class") nil nil) :type "typedef") nil [3439 3462])

This makes semantic spew errors like this one when doing idle work:
Debugger entered--Lisp error: (wrong-type-argument stringp (((0) (0) 
"PRUnichar")))
   semantic-tag-lessp-name-then-type(((((0) (0) "PRUnichar")) type

This time it is for PRUnichar but you get the picture. How to solve this?
