981213 - Restoring large amounts of deleted messages in Gmail actually marks them for deletion

Status: RESOLVED INCOMPLETE

(Thunderbird :: Untriaged, defect)

Description

[db]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/32.0.1684.0 Safari/537.36

Steps to reproduce:

I have around 50 000 messages in my "All mails" in GMail. For some reason almost all of these messages suddenly appeared as marked for deletion (I didn't do it on purpose, TB, shouldhave a warning if you try to mark more than, e.g., 10 messages for deletion).

Now I have spent a couple of days trying to Restore Deleted Messages with the only result that TB also marks messages that has arrived after the initial problem for deletion. Furthermore, some 6500 out of these 50 000 messages was unread but Restore Deleted Message, except for being broken in respect to messages deleted status, also marks unread messages as read.


Actual results:

New messages was marked for deletion

Unread messages was marked read


Expected results:

Deleted messages should be restored

Unread status must not be affacted.

Forgot to say, when I mark a few messages (I have tried with up to 250), undelete work as expected.

I upgraded, which I very rarely do, this reports importance to critical because it can/has lead to massive dataloss.

What exactly do you mean by "marked for deletion"?  
In account setting, server settings tab, is "When I delete a message" set to non-default "Just mark it as deleted"?
