(Thunderbird :: Mail Window Front End, defect)

Description

[Guido Günther]

User-Agent:       Mozilla/5.0 (X11; U; Linux ppc; en-US; rv:1.9.0.7) Gecko/2009032813 Iceweasel/3.0.7 (Debian-3.0.7-1)
Build Identifier: Mozilla 5.0 (X11; U; Linux i686; en-US; rv:1,9.1b4pre) Gecko/20090420 Thunderbird/3.b3pre

Multiple attached EMLs aren't being distinguished.

Reproducible: Always

Steps to Reproduce:
1. create an email with an attachment (test.pdf)
2. save it as test1.eml and as test2.eml
3. create a new mail that has test1.eml and test2.eml as attachments.
4. send it to yourself

Actual Results:  
5. The received email shows 4 attachments: test1.eml, test2.eml and 2 times test.pdf
6. on the received mail click on test1.eml. The opened eml window will have three attachments: two named test.pdf and one named test2.eml
7. on the received email click on test2.eml. The opened eml window wil have three attachments: two named test.pdf and one named test1.eml 
8. clicking on one of these emls will again open a window with three attachments and so on and so on.

Expected Results:  
5. the received email shows two attachments: the two attached eml files
6. on the received mail click on test1.eml. The opened eml window will have one attachment named test.pdf
7. on the received email click on test2.eml. The opened eml window wil have one attachment named test.pdf


This kind of endless loops really confuses users since they can't tell the mails apart anymore.

.eml file is attached as "Content-Type: message/rfc822;" part.
Remaining issue of bug 203570, isn't it?
Read meta bug 269826 and see Dependency tree for bug 269826.

By the way, we are probably better to open separate bug for remaining issue(s) of bug 203570, with complete test case.
