I don't understand.
Please  give method that you use to see error.

Comment 3 Marc Schmitzer 2014-11-12 18:01:58 UTC

I think I'm hitting the same problem.

A little more detailed explanation: Spamassassin has a feature where it generates a report email for each detected spam mail, and attaches the original mail to the report mail.
Kmail displays the report mail just fine and indicates the attachment. Opening the attachment with "KMail View" gives a "The file does not contain a message" error. Saving the attachement results in a zero-byte file.
Looking at the source of the report message, the attached message is there. I'll attach an example.

I just built the KDE/4.14 branch of KMail to see what the debug prints above do. In my test, the "url" print in the KMOpenMsgCommand gives "/tmp/kde-marc/kmail2s30350.index.2/unnamed". The file exists but is empty.

Comment 8 Denis Kurz 2017-01-14 14:53:14 UTC

This bug has only been reported for very old, yet unsupported versions of KMail. In more recent versions, this seems to be fixed. I tested both attached mails, and the embedded messages were shown inside the containing message, all in the same message viewer window. Tested with 5.4.1.
