120815 - Closing a tab with QuickTime crashes

Status: VERIFIED DUPLICATE of bug 66748

(Core Graveyard :: Plug-ins, defect)

Description

[Rob Yampolsky]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Win98; en-US; rv:0.9.7+) Gecko/20020111
BuildID:    2002011103

When you close a tab in which QuickTime is displaying a .png, you get a "This
application has performed an illegal operation" dialog.

Funny thing.  If you move the dialog out of the way, Mozilla continues to work
fine.  I guess it's a QuickTime bug that's caused the problem.  But when you
close that dialog, Mozilla closes.  Just verifying that it's not a Mozilla bug
per se.

I'm running QuickTime 5.0.2 on my PC.

Reproducible: Always
Steps to Reproduce:
1. Open a .png in a tab (QuickTime must be your helper for .png's - I have
QuickTime 5.0.2 - other versions may be okay)
2. Close the tab.
3. Get an illegal operation dialog.

Try this URL:

I'm not talking about a sidebar tab.  I did 'open link in a new Navigator Tab'.

I just checked, and it also happens if you just open the above URL in the main 
Navigator window and then press the Back button.

Reporter:

What is the talkback ID for your crash?

mozilla handles this fine. This is a quicktime problem. we had a bug on this...i 
will try to find it. Workaround is to use mozilla to handle this mime type 
instead of letting qt run  amok.

No, this isn't bug 103934. This sounds like a legit crash with Quicktime in a
tab browser. May have something to do with paint suppression. Anyone have a
stack trace?

[Rob Yampolsky]

Sorry.  Not running a talkback version.  Besides, I suspect it's not actually 
Mozilla that's crashing, since you can continue to work in Mozilla as long as 
you ignore the 'program has performed an illegal operation' dialog.

I just wanted somebody to verify that it's a QuickTime bug, not a Mozilla bug.  
If QuickTime crashes when running as a Mozilla plug-in, would Windows 98 close 
Mozilla when you closed the crash dialog?  That's what I think is really 
happening.

It's easy to reproduce with the URL I specified.  But may need the particular 
QuickTime 5.0.2 version.

I think Andrei might be able to comment on this. I remember him telling me once 
that an "illegal operation in plugin" is a plugin's fault and not the browser's.
It's just that we are catching some exception (earlier the browser used to crash 
when a plugin did something illegal). Now, at least we get notified with an 
error message.

This happens to me every time on Win2k whether in a tab or not (single window
open), and always after playing content handled by quicktime. I expressly
changed my prefs to make the mozilla handle .png, but even if I go to a page
that has quicktime contect embeddeded in a page (like the episode ii trailer at
http://www.starwars.com/exclusive/forbiddenlove/forbiddenlove_md.html), once you
play the content, and move to another page - crash.

I made some tests with a.m Mozilla and QT5 - mozilla did not crash any more.
Lucky chance or progress, can anyone check that ?

My own reply to #11: lucky chance, still crashes
