Uncompiled views

I've posted here a question about views that fail during the import process, but now I've realized that the problem is not related with import but with the views.

When I query the view obj looking for invalid objects, I find sometimes some views, which I compile (or just describe) and they loose their invalid status.

Today, I've done this:
EXEC DBMS_UTILITY.COMPILE_SCHEMA('myschema'); and the invalid status views have increased in number.

What the hell is wrong with this views?
