352376 - problem with user/pass rolldown windows; hang; crash...

Status: VERIFIED DUPLICATE of bug 352358

(Calendar :: Provider: ICS/WebDAV, defect)

Description

[KDS]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6

It is already known (see bug 248903 and bug 117592) that when entering passwords to access WebDAV calendars, there is a dialog (rolldown on Mac) with prefilled information and one only has to click OK.
However, it often happens (also in latest nightly build 12. sep.) that the rolldown window rolls up before one can click OK.  In such cases, Sunbird usually hangs.

Reproducible: Sometimes

Steps to Reproduce:
1. subscribe to several remote WebDAV calendars with same https authentication and certificate (preferably expired certificate, which is cheaper).
2. start up Calendar (latest build).
3. prepare to click on dialogs, watch how some disappear before you can click.
Actual Results:  
Hang.  Any attempt to quit in this state results in a crash:

ICS_NO_ERROR
[Exception... "Component returned failure code: 0x804a0100 [calIICSService.parseICS]"  nsresult: "0x804a0100 (<unknown>)"  location: "JS frame :: file:///Applications/Calendar.app/Contents/MacOS/components/calICSCalendar.js :: anonymous :: line 240"  data: no]

In addition, the Error console may come up with errors like these:
Error: this.mChannel has no properties
Source File: file:///Applications/Calendar.app/Contents/MacOS/components/calICSCalendar.js
Line: 909

Expected Results:  
Sunbird should have waited until user clicks OK.
