Invalid webresource request

[Matthew R Longhouse]

After upgrading to the 2013 Q2 controls we have been getting a large number of "This is an invalid webresource request" errors (every page access I believe) in our error reporting application.  I'm not seeing anything obviously wrong with the calendar such as missing images.

Query string:
d=oYk45SpGYUqPQWaQ_K6qeQjLI6LVoPZPDXmb2YP7w81z0o1tWAbsclqXQQzbi7yQw0YmPSHt5Mnxo3xiI8po-VlJREoNvUw_dNRIMwB1PRbPLJIwdRv3K90xKVkNfTv2lJn9SloLZWkbMqEP1Jbw3NTL5OE1&t=635096945953391250

Decoded:
pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins._Telerik.Calendar.sprite.gif

Here is the network request.  It is redirecting to our "not found" page.

It seems like this would be easy enough to verify by Telerik.  It wasn't happening before the upgrade, and the page hasn't changed.  I was hoping for some feedback before I bother with submitting a support ticket.

Hello,

 
This behavior is caused by a known bug in the Telerik skin of RadCalendar and since it is inbuilt in RadScheduler it is observed there as well. The good news is that the issue is already fixed in Q2 Service Pack 1. Please excuse us for the inconveniences caused.

Hope this will explain the issue. If you have further questions please don't hesitate to contact us again.

Regards,
Plamen
