I'm requesting blocking, although it may turn out this is expected behaviour.

You can get ForecastFox 0.9.6 from https://addons.mozilla.org/en-US/firefox/downloads/file/19254/forecastfox-0.9.6-fx+mz+ns+sm+fl.xpi

In reply to Comment #2: The problem exists with ForecastFox 0.9.6, using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b3pre) Gecko/2008011604 Minefield/3.0b3pre - Build ID: 2008011604.

Happens in Linux as well. OS -> All

The same for me... :-( Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b3pre) Gecko/2008011604 Minefield/3.0b3pre ID:2008011604

This also happens with ForecastFox Enhanced: I'm seeing this in the error console: Error: uncaught exception: [Exception... "'[JavaScript Error: "Components.stack.caller is null" {file: "chrome://forecastfox/content/parser/parser-service.js" line: 505}]' when calling method: [ffIParserService::getValue]" nsresult: "0x80570021 (NS_ERROR_XPC_JAVASCRIPT_ERROR_WITH_DETAILS)" location: "<unknown>" data: yes] Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b3pre) Gecko/2008011703 Minefield/3.0b3pre ID:2008011703

mrbkap, you able to dig into this? /be

This fixes this bug but I no longer have any way of testing bug 352791. Could somebody check to make sure this doesn't regress that bug? The problem is that we're now using the wrong context to execute component code on, leading it to not find a JS stack when it expects one. The patch avoids this by only using the context associated with the wrapper if there is no currently-running code to get in the way.

This patch also seems to fix bug 413093 and bug 413200.

Fix checked into trunk.

So, where do we get the fix from?
