See below. Could you please fix and/or upstream this? ----- Oh, so the extension isn't actually holding onto the closure it passes into native code. So the relevant data gets GCed, and it crashes. The culprit line is here: http://git.gnome.org/browse/tracker/tree/src/plugins/firefox/chrome/content/... The closure is constructed with |tracker.AsyncReadyCallback.ptr(callback_closure)|, which passes it directly into the native function without storing a reference to it. The best solution is probably to do something like: tracker.readyCallback = tracker.AsyncReadyCallback.ptr(callback_closure) tracker.connection_open_async(null, tracker.readyCallback, null); I've updated the docs to add an explicit warning to this effect: https://developer.mozilla.org/en/js-ctypes/js-ctypes_reference/Callbacks Wolfgang, can you take charge of coordinating with the gnome developers to get this fixed? ----- -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
