Thunderbird Webextensions .messages.getFull() 引发异常 0x80004005 (NS_ERROR_FAILURE)

Question

这是以下question/answer的一种跟进：

该问题末尾的代码获取帐户列表，选择 emailAccountName，从 wantedMailFolderType 获取 MessageList 对象并尝试仅从一个 messageId 获取 MessagePart 对象通过 browser.messages.getFull( messageId ) 始终失败并显示以下异常消息：

[Exception... 
"Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) 
[nsIMsgMessageService.streamMessage]"
nsresult: "0x80004005 (NS_ERROR_FAILURE)"
location: "JS frame :: resource:///modules/gloda/mimemsg.js
                    :: MsgHdrToMimeMessage
                    :: line 238"  data: no]
                       mimemsg.js:238:16

此行为在 linux mint 19.3（64 位）运行ning thunderbird 68.4.1（64 位）上相同以及 windows 7（64 位）运行ning 雷鸟 68.2.2（32 位）。

这里是重现错误的代码：

emailAccountName     = "firstname.lastname@email.com";
wantedMailFolderType = "trash";

console.log( tstamp() + " Entered Main Program" );
function tstamp () {
    let d =new Date();
    return "" + d.getMinutes() + ":" + d.getSeconds() + "." + d.getMilliseconds();
}

function accountsList_successCallback( arrayOfMailAccount ) {
    console.log( tstamp() + " Entered accountsList_successCallback()" );
    let accountId = false;
    for (let i = 0; i < arrayOfMailAccount.length; i++) {
    if ( arrayOfMailAccount[i].name == emailAccountName ) {
        accountId  = arrayOfMailAccount[i].id;
        break;
        }
    }
    console.log( tstamp() + " Leaving accountsList_successCallback(), returning accountId: " + accountId );
    return accountId;
}
function mailAccount_successCallback( mailAccount ) {
    console.log( tstamp() + " Entered mailAccount_successCallback()" );
    let mailFolder = false;
    for (let i = 0; i < mailAccount.folders.length; i++) {
    if ( mailAccount.folders[i].type == wantedMailFolderType ) {
        mailFolder = mailAccount.folders[i];
        break;
        }
    }
    console.log( tstamp() + " Leaving mailAccount_successCallback(), returning mailFolder: " + mailFolder.type );
    return mailFolder;
}
async function getMessagesList( mailFolder ) {
    console.log( tstamp() + " Entered getMessagesList()" );
    let page = await browser.messages.list( mailFolder );
    let messageHeader = page.messages[ 0 ];
    let messageId     = messageHeader.id;
    console.log( `Trying to .getFull( messageId == ${messageId} ) MessagePart object now...` );
    let messagePart = await browser.messages.getFull( messageId );
    console.log( tstamp() + " Leaving getMessagesList()" );
}

browser.accounts.list()
    .then( accountsList_successCallback)  // after .accounts.list() Promise is fulfilled...
                                          // accountsList_successCallback is called, which
                                          // in this example returns the accountId string...
    .then( accountId => browser.accounts.get( accountId ))
    .then( mailAccount_successCallback)   // after .accounts.get() Promise is fulfilled...
                                          // mailAccount_successCallback is called, which
                                          // returns the wanted MailFolder...
    .then( getMessagesList )              // ... passed to getMessagesList(), which successfully
                                          // awaits a MessageList object...
                                          // but every call to .getFull( messageId ) fails.
    .catch( finalCatch )
;

function finalCatch( error ) {
    console.error( "ERROR passed to finalCatch() : " + error);
}

console.log( tstamp() + " Leaving Main Program" );

这是最后一个运行的输出（popup.js 中的行号被删掉了，因为它们与这个摘录不匹配）：

52:40.859 Entered Main Program                                                   popup.js:xx:9

有人可以在他的机器上试试这个吗？如何进行下一步？应该报告 BugZilla 上的错误吗？

提前致谢。理查德

问题已解决！

只要且仅当另一台 PC 上的同一个 IMAP 帐户的另一个登录处于活动状态时，就会引发异常。似乎只要同一个电子邮件帐户同时有多个登录或会话，就会引发异常。

抱歉打扰了。

非常感谢您的关注。理查德
