CHttpFilterProxyInterface cause KERN-EXEC 0 error when close the session

[goodtaste]

I am debugging the HTTPExample downloaded from here and add the

CHttpFilterProxyInterface::InstallFilterL(iSession); 

after iSession.OpenL().
That works very well except that when I delete the HttpClient KERN-EXEC 0 is thrown out.

The iSession.Close() in CClientEngine::~CClientEngine() thrown the panic.

If I remove the

CHttpFilterProxyInterface::InstallFilterL(iSession); 

the iSession.Close() has no problem.

Does anyone has the same problem? I searched the forum, it seems I am the only unlucky one?
