892851 - findbar binding's constructor relies on accessibility.typeaheadfind prefs not defined in toolkit

Status: NEW

(Core :: XUL, defect)

Description

[Alex Vincent [:WeirdAl]]

In my XULRunner app, I loaded the Error Console (chrome://global/content/console.xul) as an iframe.

Error: NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getIntPref]
Source File: chrome://global/content/bindings/findbar.xml
Line: 363

The offending line is prefsvc.getIntPref("accessibility.typeaheadfind.flashBar");

The URL field shows a list of references to accessibility.typeaheadfind in the source code.  Unfortunately, the preference is not defined for the whole toolkit; the findbar widget blindly assumes the preference exists and is an integer.

The findbar widget needs some reasonable defaults for when it comes from a different XULRunner application.
