15178	Development server hangs very often when used with IE9 beta	Catalin Iacob	nobody	"For almost every request made by IE9 beta the development server hangs or results in the following stacktrace:

To reproduce this, for me it's enough to start a new project with django-admin, run the development server and try to load an URL. Sometimes it takes one or two refreshes of the page to get the exception. After the exception appears the development server is completely hung, it won't respond to requests from other browsers until it's restarted. This makes the development server totally unusable in combination with IE9 beta.

[http://groups.google.com/group/django-users/browse_thread/thread/350974a41a9637f/5b944619f9bee543 This thread] suggests that other people experience this as well.

Software versions that I used:

 * Django SVN HEAD from today (revision 15343)
 * IE9 beta
 * Python 2.6.6 32 bit
 * Windows 7 64 bit"	Uncategorized	closed	Core (Other)	1.3-beta	Normal	worksforme	ie9 development-server	Catalin Iacob	Unreviewed	0	0	0	0	0	0
