Product Version      : 0.2.149.29
Other browsers tested: 
     Safari 3: FAIL (Apple Software Updater also suffers from this issue)
    Firefox 3: OK (using "Help"->"Check for updates...")
         IE 7: OK (through Windows Update)
      Opera 9: OK (through "Help"->"Check for Updates")

What steps will reproduce the problem?
1. Open Google Chrome in a network environment with an authenticated proxy;
2. Open the tools menu's "About" (or similar) panel;

What is the expected result? 
The browser would display a notification about updates found or no new
updates available.

What happens instead?
After about two minutes displaying a "Checking for updates..." message, an
error message is displayed: "The updates server is not available (error:
7)". Additionally, the system's default browser is triggered to open a
troubleshooting page [1].

Please provide any additional information below. Attach a screenshot if
possible.
This is seen as a somehow important issue. Specially if taking into
consideration the statement in the Google Chrome blog:
  «Automatic updates are a key security feature in helping to ensure the
safety of Google Chrome users.» [2]
As this issue will prevent Google Chrome from updating itself, less
experienced and/or proactive users will potentially be using a browser
version which is vulnerable to attacks, so this issue can almost be
considered a security bug.

Note that this issue makes little sense considering the browser itself
reasonably (not perfectly [3]) supports authenticated proxy.

A related issue [4] exists at the installer level, therefore preventing
users in a similar environment to be able to install the browser.

Attached are a screenshot of the about panel containing the error message
(in Portuguese) and the error logged in the Event viewer.
