Comment 55 for bug 849416

What is the current status on this problem?

With SeaMonkey 2.10 a multipart/alternative message with text, html and test/calendar parts (as produced by Outlook and Google Calendar) shows as the text part in the mail pane and a "meeting.ics" file in the attachment pane which cannot be opened or saved. When the "View -> Message Body as -> All body parts" trick is used, all parts are shown in the attachment pane and the meeting.ics can be opened or saved.
While cumbersome, it is usable as a workaround to access the meeting.ics (which we can import into the calendar app we use - not lightning)

However, in SeaMonkey 2.11 and 2.12 the attachment pane no longer shows up when a message like this is opened. I'm sure I have read a bug (for Thunderbird) that discussed this change, but now I can no longer find it.

Unfortunately this means that our users no longer see the trigger to try the "all body parts" workaround when they receive a message (the nonfunctional meeting.ics attachment). So we have been unable to upgrade past 2.10.
Today I installed 2.13beta and unfortunately it has not been fixed.

We need either the old behaviour which we can use with the workaround, or better the solution depicted above (which I understand will mean that we see the text part in the message pane and the text/calendar part as an attachment in the attachement pane where it can be saved without using "View -> Message Body as -> All body parts")

Any idea in what version we can expect this fix? (e.g. the one in comment #25)
