IMessage::OpenProperty has an hidden call to CoInitialize?   

I am working on an application that uses MAPI to access E-Mail.  

I recently noticed that calls to CoInitialize / CoUninitialize becomes 
unbalanced after accessing a message's content through the following call:

m_spIMessage->OpenProperty(
        PR_RTF_COMPRESSED, &IID_IStream, 0, 0, &cpUnknown);

Any idea?
