909976 - The application quits unexpectedly after a few 'WARNING: requested removal of nonexistent window' and 'ASSERTION: consider quit stopper out of bounds'

Status: NEW

(Toolkit :: Startup and Profile System, defect, P5)

Description

[Florian Quèze [:florian]]

Steps to reproduce:
- in about:config, set "browser.chromeURL" to an empty string. (This has no reason to happen in Firefox by default, but I think it's reasonable for this preference to not be set in XUL applications that don't expose a browser, and handle all http links through nsIExternalProtocolService).
- open the Browser console, enter: window.open() and press enter. Repeat this step several times (typically 3 or 4) until the application quits for no apparent reason.


In a debug build, each time window.open() is entered in the browser console, these messages will be printed to the terminal:

Couldn't convert chrome URL: chrome://navigator/content/navigator.xul

WARNING: NS_ENSURE_SUCCESS(rv, rv) failed with result 0x80004005: file .../dom/base/nsGlobalWindow.cpp, line 10111


Once window.open() has been executed as many times as there were opened window, this assertion will be printed once for each window that actually existed:
###!!! ASSERTION: consider quit stopper out of bounds: 'mConsiderQuitStopper > 0', file .../toolkit/components/startup/nsAppStartup.cpp, line 498

And the application quits "cleanly" (it doesn't crash).
