Git over HTTPS no longer completes when behind proxy

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Git 1.7.10-preview20120409 
https://code.google.com/p/msysgit/downloads/detail?name=Git-1.7.10-preview201204
09.exe&can=2&q= on a machine that is behind a corporate style proxy
2. execute: git clone https://username@github.com/username/project.git for a 
github project


What is the expected output? What do you see instead?
I expect the project to be cloned onto my machine.

I expect to see the following which is what I get when I have 
Git-1.7.9-preview20120201 installed:

Cloning into 'D:\projects\project'...
POST git-upload-pack (524 bytes)
remote: Compressing objects: 100% (1202/1202)
Receiving objects: 100% (2486/2486), 18.39 MiB | 289 KiB/s

Checking out files: 100% (561/561)
Checking out files: 100% (561/561), done.
Success

Instead I see this when I have Git-1.7.10-preview20120409 installed:
Cloning into 'D:\projects\project'...
POST git-upload-pack (524 bytes)
remote: Compressing objects: 100% (1202/1202)
Receiving objects: 100% (2486/2486), 18.45 MiB | 275 KiB/s

Resolving deltas: 100% (1553/1553), done.
remote: Total 2486 (delta 1553), reused 1979 (delta 1123)

No matter how long I wait it never finishes.

What version of the product are you using? On what operating system?
Git-1.7.10-preview20120409 on Windows XP SP3

Please provide any additional information below.
I don't know much about the proxy that is in place so I'm not sure how much 
more help I can provide.

I have the same problem with git 1.7.11.msysgit.1 on Windows 7

It works fine without a proxy ( http, https, git )

But with the corporate proxy it works only with http.
With https it is frozen just afer "Resolving deltas: 100% (154/154), done.
( it never finishes )

Launched with bash ( .sh file )
