Proxy Authentication don't work

[Skysurfer14]

On my work-PC (win7 SP1, 64Bit) the proxy authentication did not work, tested with version 1.4.1 and 1.4.2. It's same using system proxy or manualy set user/password. With Wireshark I've seen a difference between connections from owncloud client and chrome browser:

owncloud client:

CONNECT domotics.xxxxx.de:80 HTTP/1.1
Proxy-Connection: keep-alive
User-Agent: Mozilla/5.0 (Windows) mirall/1.4.2
Host: domotics.xxxxx.de

HTTP/1.1 407 Proxy Authentication Required
Mime-Version: 1.0
Date: Wed, 04 Dec 2013 08:50:19 CET
Content-Type: text/html
Proxy-Authenticate: NTLM
Proxy-Authenticate: Basic realm="IronPort Web Security Appliance"
Connection: close
Proxy-Connection: close
Content-Length: 2128

Followed by an HTML-Page with an error message "Proxy Authentication Required"

Chrome:
