59163 - Browser crash after clicking 'Ok' to "No Plugin Downloader Plugin!" message box

Status: RESOLVED DUPLICATE of bug 59426

(Core :: Layout, defect, P3)

Description

[Al Papp]

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)
BuildID:    2000110410

I try to load the page http://www4.ncsu.edu/~bwmott/www/2600/

The page begins to display the background at which point a Message Box comes up 
with the title "No Plugin Downloader Plugin!" and the following text (my 
quotes):

"Netscape cannot find the Plugin Downloader Plugin.  Without the Plugin 
Downloader
Plugin, you cannot automatically download and install plugins.  Please visit
http://www.netscape.com/ to install the Plugin Downloader Plugin.

( ) I know I need the Plugin Downloader Plugin, but don't show me this dialog 
again."

I leave this check box unchecked, and click the 'OK' button.  At this point, I 
get NT's "Dr. Watson for NT" message box with the text "An application error 
has occurred and an application error log is being generated.  mozilla.exe 
Exception: access violation (0xc0000005), Address: 0x01a5e5a5".  

Note that if I do not click "Ok" in the original "No Plugin Downloader Plugin!" 
message box, the web page appears to load up file.  However, some time later if 
I click the "Ok" button of the "No Plugin Downloader Plugin!" message box (to 
dismiss it) then mozilla.exe crashes at that point.


Dr. Watson Crash message box appears in Win NT.



Reproducible: Always
Steps to Reproduce:
1. Load http://www4.ncsu.edu/~bwmott/www/2600/
2. When the "No Plugin Downloader Plugin!" message box comes up, click the "Ok" 
button.  Mozilla crashes at this point.


Actual Results:  Mozilla crashes and NT gives a Dr. Watson.

Expected Results:  The web page should load without displaying the plugin (for 
which I have no displayer).  I should be able to continue to web surf in that 
window.

confirmed with trunk 110604 win32 talkback build on NT4.  Looks like Layout and
maybe Troy

This has the same stack as bug 59426.  I suspect this has less to do with the
plugin downloader plugin than with the issues described there.  It's probably a
duplicate.

Just marking as a dup.  If you disagree, please reopen.

The problem isn't exactly the same, but it is probably related to a missing
