55420 - Crash in ViewportFrame::Destroy when cancel plugin download window

Status: VERIFIED DUPLICATE of bug 54868

(Core Graveyard :: Plug-ins, defect, P3)

Description

[Tom Everingham]

Overview Description:  When I select 'cancel' from the confirm dialog 
(confirming whether or not I want to download the RealPlayer plug-in) I crash.  
I do not have the real player plug-in installed for NS6 and didn't want to add 
it. 

Steps to Reproduce:
1.)  Go to url
2.)  Select video to view (Streets of Belgrade for today)
3.)  If you don't have a real player plugin you will get a 'confirm' dialog with 
the message 'We have detected that you do not have RealPlayerer installed on 
your system.  Would you like to download it now?"   Select Cancel.

Actual Results:  Crash

Expected Results:  Shouldn't crash

Build Date & Platform Bug Found:  Windows NT 2000100508
Also happens on Linux rh 6

cc:ekrock. I see this too with the latest plugin provided by REAL today on 
windows branch build. PLS NOTE :Even if the plugin is installed, the message 
mentioned in step 3 pops up.

keyword: rtm. cbsnews.com is a widely visited page.

Do we have a separate bug on 'Plugin is not detected on this site'?

Comment 5

[av (gone)]

Yes, we do. And that part will not be fixed in Mozilla.

Steve, I found that it crashes in the view system during tearing down when 
accessing freed pointer. Could you please have a look? Do you think this could 
fixed for rtm?
