When a multipart/alternative has both text/html and text/calendar content, Mozilla displays the text/calendar instead of text/html. text/calendar (generated by the Outlook calendar) is not a known type to Mozilla and it does not know how to display it properly. Mozilla should favor types it knows to type if doesn't know, and display the text/html intead of the text/calendar. Step for reproduction : - display the mail message that I include as an attachment.

this is a dup of bug 83262 which has been fixed last week. Please try with a recent build. BTW, which build are you using? *** This bug has been marked as a duplicate of 83262 ***

I'm using : Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:0.9.9) Gecko/20020311 If it has been resolved, then it hasn't been checked in the 0.9.9 branch. Bug 83262 is "Scrollbar on preferences dialog doesn't sync" and has no relationship with this problem, maybe one of the digits is wrong. I tried hard to find a duplicate, and even did some searches on closed bugs, but did not see one.

Right, the fix it's only on the trunk (1.0)
