When I open the extensions manager in my Xul app using:


app = "chrome://mozapps/content/extensions/extensions.xul";
window.open(app,'Test','chrome, width=640, height=480').moveTo(0,0);

I get the following error in the javascript console:

Error: uncaught exception: [Exception... "Component returned failure code:
0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch2.getBoolPref]" nsresult:
"0x8000ffff (NS_ERROR_UNEXPECTED)" location: "JS frame ::
chrome://mozapps/content/extensions/extensions.js :: updateGlobalCommands ::
line 2388" data: no]

Any idea what's this?

ps. The extensions manager opens and works well, but I'm worried with this
error message.
