+Subject: [PATCH] Fix possible crash when downloading attachments
+
+Turns out we've been happily deleting network replies from the
+QNetworkReply::finished(). That was never a good thing to do, but it did
+not use to crash with older Qt. Now it does.
+
+After changing to deleteLater(), there's a window for
+already-deregistered replies to generate events, therefore the assert
+has to go, too, otherwise Bad Things happen:
