309584 - If IMAP expunge enabled and proxy disappears, TB does not exit correctly

Status: RESOLVED DUPLICATE of bug 292939

(Thunderbird :: General, defect)

Description

[David Mytton]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.12) Gecko/20050915 Firefox/1.0.7

I am accessing Thunderbird using a proxy and then using a tool to tunnel the TB
connection through that proxy. I am using the HTTP-Tunnel proxy
(www.http-tunnel.com) installed on my PC and SocksCap
(http://www.socks.nec.com/Download/SocksCapDownload/index.asp) to launch TB and
handle the tunnelling.

I am using IMAP for both of the two mail accounts I have set up in TB. Both of
these have the Server Settings > Clean up ("Expunge") Inbox on Exit option enabled.

If the proxy then disappears (e.g. I close both SocksCap and HTTP-Tunnel) and
then close TB, the thunderbird.exe process remains running. After a short time,
a TB error appears saying the connection to my mail server has been refused - it
can't connect because the proxy is no longer running. Clicking OK clears this
error. After another short period of time, the error appears again. However,
after clicking OK this time, the thunderbird.exe process exits correctly.

Reproducible: Always

Steps to Reproduce:
1. Download and install HTTP-Tunnel and SocksCap
2. Launch TB using SocksCap
3. Make sure you have an IMAP account with the Expunge option enabled
4. Close HTTP-Tunnel and then SocksCap
5. Close TB. 
Actual Results:  
The thunderbird.exe process still exists and the error messages appear twice.

Expected Results:  
TB should have closed immediately

Using TB version 1.6a1 (20050921)
