When running the simple sample in #427866 or the gluezilla Test
(gluezilla/test/browser -- you'll have to replace Mono.Mozilla with
Mono.WebBrowser in the Makefile, make test.exe, make test for it to run), when
browser.Navigate () is called, the WebBrowser control spins the cursor and
hangs without loading the actual page.  I've tried various URLs:
http://www.google.com, http://www.mono-project.com, etc and all display the
same behavior.

I'm experiencing this on r125914 of mono-2-4 branch.  The test case works
reasonably well on Mono 2.0.1.

Here's what I get when I -SIGQUIT the app while the cursor spins:
