Opening an order in CRM 2013 sometimes gives a blank page

Question

Sometimes CRM 2013 decides to give me the following error when opening an Order (and presents me with an empty page, but with the top navigation bar intact):

<CrmScriptErrorReport>

This will keep on happening until I fiddle around with the cache or open another organisation. I'm still not sure what exactly resolves it. I do have custom code on the Order form but I often go days without getting the error. Any idea how I can try to locate the cause of this error and whether it has something to do with my custom code or whether its a bug in CRM 2013?

Thanks.

we are experiencing the same issue, so it's probably safe to say it's a CRM 2013 bug. IISRESET is the simplest way to clear the issue we've found (we're not multi-tenanted though), could you elaborate at all on how you poked the cache? – Gadabout

I've faced same issue with quote entity, when I ask my CRM users to clean temporary files for the browsers they never reported the issue.
