1735049 - mid URLs in email bodies do not resolve

Status: RESOLVED DUPLICATE of bug 1723645

(Thunderbird :: Untriaged, defect)

Description

[nathanielmbeaver]

Attachment: mid_URL_test_-_2021-10-09.eml

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:93.0) Gecko/20100101 Firefox/93.0

Steps to reproduce:

1. Send an email to myself containing this mid URL:

mid:f8051cc[e-mail]

2. Open the message containing the mid URL.

3. Click on the mid URL in the message body.

Actual results:

The message corresponding to the mid URL did not open. I got this console output:

IPDL protocol error: Handler returned error code!

###!!! [Parent][DispatchAsyncMessage] Error: PClientManager::Msg_ForgetFutureClientSource Processing error: message was deserialized, but the handler returned false (indicating failure)

Expected results:

The message corresponding to the mid URL should open, in this case an email on 2020-12-29 from [e-mail] with subject "New Year, New Inbox".

I know that this should work because when I open it from the command line like this, it opens the corresponding message in a new tab just fine:

thunderbird mid:f8051cc[e-mail]

Similarly, when I open it with xdg-open, it opens just fine also:

xdg-open mid:f8051cc[e-mail]

It's supposed to be fixed by bug 1724292, but I don't know why it doesn't work on 91. From what I see,
Cc["@mozilla.org/uriloader/content-handler;1?type=application/x-mid"].createInstance(Ci.nsIContentHandler) works on trunk but not on 91, that means somehow MidContentHandler is not registered correctly on 91.

Thanks for the update, I can confirm that internal mid links work fine for me with the 94.0b2 beta.

91.2.1 will include the fix, thanks.
