Attachment: Possible patch

I glanced at the testcase here and there might be a really simple fix.  We grab a reference to a CPOW and then wait for focus. However, in the meantime, nothing stops us from collecting the CPOW out from under us.  This patch reduces the amount of time that we need the CPOW alive for, which should hopefully stop this bug from reoccuring.

While I was here, I took the opportunity to silence a "no charset declared" warning.
