61249 - NT 2000 paste "copy shortcut" from internet explorer prevents mozilla.exe death

Status: RESOLVED WORKSFORME

(Core :: XUL, defect, P3)

Description

[jbrunette]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; m18) Gecko/20001126
BuildID:    2000112620

When I open a web page in Internet Explorer, right-click a link in the web page
and select "Copy Shortcut" from the menu that appears, then Paste that into
Mozilla's address/location bar, the mozilla.exe process will not die when the
browser is closed.

The mere act of Pasting the shortcut to the address/location bar (either via
right-click or CTRL-V or from the Edit menu) is sufficient...you need not hit
Enter for the problem to exist.


Reproducible: Always
Steps to Reproduce:
1). Open Internet Explorer.
2). Access your favorite web site.
3). Right-click a link in the web page.
4). Select "Copy Shortcut" from the menu that appears.
5). Open Mozilla.
6). Paste the address into the address/location bar of Mozilla.
7). Close the Mozilla web browser window.


Actual Results:  The mozilla.exe process remains in memory after the web browser
was closed.


Expected Results:  The mozilla.exe process should just unload.


This was tested on Windows NT SP6a with Internet Explorer 5.5 SP1 and Windows
2000 (no sp) with Internet Explorer 5.5 SP1.

Various Mozilla builds since 10/26/2000 (up to 2000112620) have been tested and
found affected.

Windows 98 was also tested but mozilla.exe unloaded normally, so this may be
restricted to NT/2000.

==============

When the Mozilla browser is closed, mozilla.exe consumes all processor power for
a few seconds (AMD K6 333Mhz) then unloads.  When this bug is exploited,
however, mozilla.exe consumses the processor like it normally does but doesn't
unload afteword and sits idle.

==============

Additionally, trying to open Mozilla while the dormant mozilla.exe process is
still in memory produces the following error:

mozilla.exe - Application Error

The instruction at "0x60d0e4e5" referenced memory at "0x002f6538".  The memory
could not be "read".

Once OK'd, Mozilla opens normally when tried again.  However, the bug still
exists in subsequent Mozilla processes.

confirmed with 112704 mozilla build on NT. Strange clipboard behavior.  Over to
Toolkit for investigation.

interesting bug report!  I can't reproduce this on Win98 though, so ->pinkerton
for further triage

wonderful. probably an OLE refcount bug. also probably not that common.

does this still happen with ie6? my guess is that there's some weird os bug
here, since it works in 98, and works with every other app, right? it it just IE
that causes this? all we're doing is pasting regular text.

does it only happen when you copy a shortcut? does it also happen when you just
select text in a webpage?

pushing off.

With current mozilla trunk, and IE5.5 on win2k, I cannot reproduce this failure 
to exit mozilla.exe. The app quits normally for the steps to reproduce above. 
[Note: the original bug report is for IE5.5 as well, not IE6.0].

Haven't looked at this in quite a while.  Hmm...in attempts to reproduce this 
again, tested mozilla 0.6 and 0.7, both of which has this problem, but 0.8, 
0.8.1 and 0.9 do not.  Didn't test other versions, but I'm guessing this was 
probably fixed indirectly back in 0.8.

Someone want to verify and close?
