Attempting to open the Add ons Manager fails in Linux trunk debug builds but succeeds on Linux opt and Windows/Mac opt and debug builds. Steps to reproduce: 1. Click Tools. 2. Click Add-ons. Expected Result: Add-ons Manager opens Actual Result: Add-ons Manager does not open and the following appears in the error console: Error: uncaught exception: [Exception... "Component returned failure code: 0xbf972704 [nsIDOMJSWindow.openDialog]" nsresult: "0xbf972704 (<unknown>)" location: "JS frame :: chrome://browser/content/browser.js :: BrowserOpenAddonsMgr :: line 4702" data: no] I'm not sure when this regressed but I could reproduce it with this morning's debug builds evening after clobbering/rebuilding and rm -fR the objdir and rebuilding.

hmmm, maybe more general than just the addons mgr since Help->About Minefield is giving Error: uncaught exception: [Exception... "Component returned failure code: 0xbf972914 [nsIDOMJSWindow.openDialog]" nsresult: "0xbf972914 (<unknown>)" location: "JS frame :: chrome://browser/content/utilityOverlay.js :: openAboutDialog :: line 318" data: no]

how did a f'ing miss that one! doh.
