I don't have an account set up in my Mozilla profile, because I don't use Mail/News. If I accidentally click on a mailto: link, a Mail composer window comes up with a "New Account Setup" pop-up. I click "Cancel" and a "Are you sure you want to exit?" pop-up appears. If I click "Cancel" again, the "New Account Setup" dialogue reappears and then the whole application crashes. This is 100% reproducible on my system.

I have just confirmed that this DOES NOT happen when I open the Mail/News window explicitly from the Window menu. It only happens when Mail/News is implicitly opened by a "mailto:" link.

I'm sorry, I forgot the Build ID: 2002052918, running on Mac OS 10.1.5.

When I do this I get the Create New Account dialogue. When I click cancel - it just cancels :-). Are you sure you want to exit is not asked. Tested by clicking on your name above. Mozilla 2002071403 Mac OS X 10.1.5

Christopher, can you please attach a crash report (stack trace) generated by this crash?

Here's the highlights from the stack trace: Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000794 Thread 0 Crashed: #0 0x00000794 in 0x794 #1 0x01efd110 in nsToolkit::GetTopWidget(OpaqueWindowPtr *, nsIWidget **) #2 0x01f13a90 in nsMacMessagePump::DoActivate(EventRecord &) #3 0x01f12a8c in nsMacMessagePump::DispatchEvent(int, EventRecord *) #4 0x01f12628 in nsAppShell::DispatchNativeEvent(int, void *) #5 0x01e4904c in nsXULWindow::ShowModal(void) #6 0x01e316c0 in nsWebShellWindow::ShowModal(void) #7 0x01e45d6c in nsContentTreeOwner::ShowAsModal(void) #8 0x01dd13f8 in nsWindowWatcher::OpenWindowJS(nsIDOMWindow *, char const *, char const *, char const *, int, unsigned int, long *, *) #9 0x028342d0 in OpenInternal__16GlobalWindowImplFRC9nsAStringRC9nsAStringRC9ns #10 0x0282f02c in GlobalWindowImpl::OpenDialog(nsIDOMWindow **) #11 0x005bce9c in XPTC_InvokeByIndex #12 0x005bcd90 in XPTC_InvokeByIndex #13 0x01c55594 in 0x1c55594 #14 0x01c5ba2c in XPC_WN_CallMethod(JSContext *, JSObject *, unsigned int, long *, long *) #15 0x01bd4c1c in js_Invoke #16 0x01bdccc4 in 0x1bdccc4 #17 0x01bd5110 in js_Execute #18 0x01bb5c4c in JS_EvaluateUCScriptForPrincipals #19 0x0281f164 in nsJSContext::EvaluateString(nsAString const &, void *, nsIPrincipal *, char const *) #20 0x0283529c in GlobalWindowImpl::RunTimeout(nsTimeoutImpl *) #21 0x02835ec0 in GlobalWindowImpl::TimerCallback(nsITimer *, void *) #22 0x00627804 in nsTimerImpl::Fire(void) #23 0x006279b8 in handleTimerEvent(TimerEventType *)

sounds identical to bug 138462, except you are crashing (that bug has a JS exception where you crash). I don't know why you're crashing, but I would bet that the patch in that bug would fix your problems as it would never get to that point (if nothing else).

This is a duplicate of bug 144908.
