838213 - Thunderbird deadlocks when in "Save All" screen while another thread downloads duplicately named attachments

Status: RESOLVED DUPLICATE of bug 530608

(Thunderbird :: Untriaged, defect)

Description

[David]

Attachment: These were the two windows opened simultaneously. Didn't save the full screen, because there would have been too much to redact, but should illustrate the point.

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_2) AppleWebKit/537.17 (KHTML, like Gecko) Chrome/24.0.1312.57 Safari/537.17

Steps to reproduce:

I had two emails from the same person with a bunch of attachments:

Email 1 had 21 attachments at 18.5MB (two of these files had the exact same filename for whatever reason)
Email 2 had 24 attachments at 10.6MB.  

I selected "Save All" on email 1.  While email 1 was still saving clicked the "Save All" button on email 2. 

I was able to reproduce this bug three times on Mac - Mountain Lion and am running Thunderbird, 17.0.2.


Actual results:

Since Email 1 had two attachments named the exact same thing, while I was still browsing for a folder to save the files for email 2, a "File already exists" error popped up behind the save window for the duplicate file in email 1. 

I tried to specify a save path and it wouldn't let me, I'm assuming because there was a lock being issued by the error message.   But the error message was not clickable either, I'm assuming because the save window takes precedence.  

I couldn't even cancel out of the save window.   I was just stuck with two windows open and couldn't even exit out of the program nicely.  I had to run a "Force Quit" to be able to get back to using Thunderbird.


Expected results:

It should have either allowed me to click the buttons on the "duplicate file" window, or allowed me to continuing specifying a save path for email 2.
