The viewer will display icons incorrectly for attachments with an unknown content-type: Example: Content-Type: application/x-outlook-tnef Instead of the "unknown" icon, the viewer displays something that looks like the icon can't be loaded
I cannot reproduce this behaviour. When the attached file's mime type is unknown, I get a icon for binary data mime type. Maybe this should be marked as closed?
Created attachment 55454 [details] Sample mail that shows the problem Still happens to me, see the attached mail as an example source of the bug. You can import it into KMail with File->Import Messages (choose mbox format and some target folder)
I can confirm this bug will look at where is code to fix it. Regards.
Fixed in 4.7.1 or 4.7.2 and master
