Mail contents get lost for mails with (probably) identical ID; mail headers for one of those appears duplicated instead

I received 3 mails from a person, which probably had the same message id, no
summary and some attachments. I could read the mails once, but after leaving thunderbird and restarting all those messages appeared to be identical afterwards. Now I see 3 identical mails of that sender in thunderbird (all with same sending date and identical content) instead of 3 different mails (from different dates with different content). The contents of the other 2 mails is not visible anywhere.

I tried to search for the content of the other mail with the searching function, and thunderbird was able to locate that content in the original mail (which was listed in the search result), but when I tried to open that, an empty window appeared.

I read that older versions of thunderbird already had some problems with mails of identical id.

Reproducible: Didn't try

Steps to Reproduce:
1.As this probably requires multiple different mails with identical ids, I do not know how to reproduce this.
are you using IMAP or POP3? We generally allow multiple messages with the same message-id but there are places where we assume that they're the same message.

I use a POP3 account. As I wrote, directly after receiving a new (of those) identical mails, it was separately viewable; after exiting thunderbird and restarting it, the new message (with same id) was "replaced" by an identical copy of the first message (with same id). It was in the same place (still the inbox of thunderbird), but at a different time.

Is there any way to get the different contents of the original messages with same id back and get rid of the identical copies?
I'm not really sure what's going on, but you could try rebuilding the index (folder | properties, rebuild index).

Are you viewing the messages in their own window, or in the normal 3-pane window?
I tried both variants, but regardless which of the 3 messages I select to view, I always get the same content (original content of the first of the 3 messages).

I also tried rebuilding the index as you suggested, but this did not improve anything.

I then tried the function "edit as new" for one of the messgaes; this lead to a crash of thunderbird:

Maybe the index rebuilding did change something; now I found one of the other messages separately (but I still have the 3 identical message headers remainining pointing all to the same message content).
do you still see this problem in current updates of version2 ?
