What are the possible reasons for Facebook “Application Validation Error”?

Question

My application uses the Facebook API to display user information via / me, / wall, etc.

Sometimes users encounter an error:

    "error": {
        "message": "Error validating application.", 
        "type": "OAuthException", 
        "code": 190
    }

I can not find the reasons why this may be caused as:

• The access current is valid, never expires and is associated with my application.
• I got permissions for API calls
• API calls work fine after

In this condition, what can cause this?
