630801 - Broken error page with pushState, exceptions

Status: NEW

(Core :: DOM: Navigation, defect)

Description

[Jesse Ruderman]

Clicking the button in this testcase produces a broken error page, which shows no text other than "Or you can add an exception…" and "Try Again".

The weird part is that the pushState has an effect on the other window, even though it throws.

Might be related to bug 608815.

I can't reproduce this bug with the attached testcase. WFM?

Instead, the error console shows

Error: uncaught exception: [Exception... "Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIDOMHistory.pushState]"  nsresult: "0x8000ffff (NS_ERROR_UNEXPECTED)"  location: "JS frame :: file:///aaaa/bbbb/cccc/b2.html :: boom :: line 9"  data: no]

If this error message implies it's due to owner's privilege violation, there's no problem. Otherwise, for example, pushState doesn't support JSON any longer etc. , we need a new testcase.

I get the same error when I save the page locally.  It does bring up an error page, file:///404, but the page looks fine...
