Status: RESOLVED DUPLICATE of bug 351224

(Thunderbird :: Message Reader UI, defect)

I've got thunderbird-3.0.3-1.fc12.x86_64 and I'm up-to-date from F13 alpha, but this is a long-standing problem.

Some charming individual decided to send me an email message with a 12MB attachment.  Idiot.

So I tried to deleted it in thunderbird.  When I try to do this, and I've had this problem often in the past, thunderbird thinks about it for a long time, and I think it's consuming a huge amount of network bandwidth while doing so, and in the end, the attachment *may* end up deleted or it may not.  I don't know what the heck is going on, but it makes no sense.

When I remove the attachment in Outlook, it's gone immediately.  Presto, done, no muss, no fuss.  There's no reason why thunderbird shouldn't be able to do the same thing.

I wasn't able to reproduce this in my test with Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.1.9) Gecko/20100317 Lightning/1.0b1 Thunderbird/3.0.4 ID:20100317103207 -- TB removed the 10MiB attachment within a second.

Probably this is somewhat of an intermittent bug. Can you attach an IMAP protocol log to this bug, following the directions at <https://wiki.mozilla.org/MailNews:Logging>? (It'll help if you can turn off automatic mail download/retrieval in Account Settings, because otherwise the log will get rather full quickly.)

Attachment: sample message which exhibits this problem

On second thought, this doesn't appear to be about message size, it appears to be about the format of the message being edited.

In particular, the attached message, whose MIME type is multipart/alternative, exhibits this problem.  If you try to delete the attachment foo.pdf, Thunderbird acts like it's deleting the attachment but actually doesn't.

If you modify the message by replacing multipart/alternative with multipart/mixed in the header, then deleting foo.pdf works just fine.

This may be bug 417646.

If not the same, then certainly a related bug.  And pretty incredible that that bug has been around for over two years and still isn't fixed!
