+1 from reading (applicable also for 4.1)

I think we wanted to add some "real" mime type global detection, but 
alas we didn't manage to get it into 4.2. So for me this change is ok as 
well. It's more likely to send PDF files per mail than Flash files => +1

Sidenote: It's odd that getExtendedURL calls getURL without headers and 
will call for unknown types getURL (in getMimeType) again, this times 
"headers only".
