The same happens when I try to `edit message as new'. Reproducible: Always Steps to Reproduce: 1. Open attached email message 2. Click `Forward' or `Edit message as new' Actual Results: The attachment disappeared and the original body went into an attachment Expected Results: The attachment should remain an attachment and the original body should remain inline

This is an anonymized version of the message which causes the problem. It still does cause the problem.

STR (tested on TB12.0.1/WinXP) 1 Open .eml of attachment 450838 [details] with TB 2 Forward inline or Edit as new Actual result (slightly different from comment 0, reported against TB3) 1 msg displays "correctly", with plaintext body text and 1 attached .pdf 2 a) body text disappears when forwarding inline (confirming this bug) b) attachment disappears (Bug 558128) Expected 2 a) keep body text when forwarding inline b) keep attachment when forwarding inline Explanation: Looking at testcase.eml of attachment 450838 [details]: 2 a) "missing body on forward inline" occurs because body part is Content-Type:text; changing that to Content-Type:text/plain fixes that problem. However, if we display the "text;" body correctly, we also need to forward it. > --------------c2997eda0922b9fff775d5489ccac0af > Content-Type: text; charset=ISO-8859-1 > Content-Transfer-Encoding: 7bit > > This was message body 2 b) this looks like duplicate in support of Bug 558128: parts of multipart/related that are not referenced from main part get lost when forwarding. Further notes: - pdf attachment is broken/incomplete (but that shouldn't matter) - final boundary missing (but adding it doesn't help)
