+Subject: [PATCH] QHttpMultiPart: fix data corruption in readData method
+
+When readData() is called repeatedly, we need to keep track which
+part of the multipart message we are currently reading from.
+Hereby we also need to take the boundary size into account, and not
+only the size of the multipart; otherwise we would skip a not
+completely read part. This would then later lead to advancing the
+read pointer by negative indexes and data loss.
+
