Camino 2003080502 trunk

Ok... this report is kind of weak... shoot me

- Filing in Camino as thats where I had the crash, but I suspect its a Mozilla bug
- I don't have cookie notifications on so I don't know what site crashed me, but
I'll go through my history in a bit and see if i can repro anywhere

Relevant stack (attaching a full stack in a minute):

i don't see this happening on the trunk mozilla build with my recent HTTP
changes.  i don't have a mac to test this out on.

saari@netscape.com is also a dead email address.... this needs to have a better

I've been experiencing the same thing in Mozilla/5.0 (Macintosh; U; PPC Mac OS X
Mach-O; en-US; rv:1.5b) Gecko/20030805 Camino/0.7+ . So far it's only occured on
sites for which I've specifically denied all cookies. The crash log is almost
exactly the same (though for some reason I'm getting odd characters in place of
the parens and such).

Here's the latest crashlog, from visiting http://www.threadless.com/ .

ok.. confirming... crashed on my first vist in camino to the threadless address
(and one other time that I can't pin down to a site.. actually think it may have
been an ad pushing a cookie as Camino wasn't even in focus at the time of the crash)

did not crash on subsequent visits in 08-05-02... i'm clearing my cookies and
gonna run with 08-04-02 and seamonkey 08-05-03 for a bit
Ever confirmed: true

hmm... that site uses flash... i wonder if that could be related to this problem.

in fact, the only way i can think of that that function would crash is if the
GetInterface method returned NS_OK with a NULL valued out param.  hmm... could
it be that some part of the flash plugin is implementing GetInterface??  hmm...

it might help to see what URL is being loaded... we can learn that from a HTTP
log.  instructions for capturing a HTTP log are available here:

I don't believe so, as I had it happen a few times yesterday when I was trying
to view an image at members.msn.com . I did check, and the server was indeed
trying to send me a cookie.

i tried visiting the site using the 2003-08-06 linux trunk w/ flash installed,
and i could not repro the crash.  if you can repro under OSX, then please
capture a HTTP log.  thanks!

OK. I have a log.

This is from Sprint PCS's billpayment. It was trying to pop open a window at the same time. Also, in 
the terminal window, I got the message:

[nightstalker:Camino.app/Contents/MacOS] avidriss% ./Camino 
2003-08-07 19:24:13.338 Camino[1057] JS error: Security Error: Content at https://

from https://nj25.speedpay.com/myaccount_payments.asp.
Bus error

... if that matters. Let me trim the file a bit, take out the secure info, and I'll attach it.

HTTP log

I visited sprintpcs.com, logged in, selected to pay my bill, and then clicked
on an "online check" link. A window popped up, the status bar said it was
loading from nj25.speedpay.com, and then it blew up.

It's probably only the last 40k that matters, but here you go. Good luck.

avi: it would actually be helpful to me if i could see the full HTTP log...


if you want you can just email it to me directly.  thanks!
At http://lxr.mozilla.org/mozilla/source/netwerk/base/src/nsLoadGroup.cpp#770
nsLoadGroup::GetNotificationCallbacks always returns NS_OK, even when the result
value is null. At
that (maybe null) value is used, without checking.
Could that be the problem?

###!!! ASSERTION: You can't dereference a NULL nsCOMPtr with operator->().:

So this is a nullpointer. However, the line number looks odd.

v1 patch

patch to shore up notification callback handling...

mvl: yeah, you are right.  if the load group does not have a notification
callback then it would return NS_OK and a NULL out param.  and, moreover that
is completely OK for the load group to do.  so, we do need a fix in
nsHttpChannel.	a simple NULL check would suffice, but i decided to simplify
GetCallback some what in the process.

Following from comment 15, which line number looks odd? I have probably edited
the file concerned.

My line 799 is
"                rv = cbs->GetInterface(aIID, aResult);",
the official line 793 .

How are popke getting logs? Does the ENVIRONMENT file system sill work?

Rightly or wrongly, I don't check *aResult until after the assignment to
it ... Perhaps the value should be checked at that point ...

This tends to indicate that the root of this bug is where we think that
it is.

requesting approval to crash fix for 1.5 beta.	fix is low risk.  while this
bug report only sites a crash in camino, i believe this crash is possible in

I have encountered this bug as well.

It was fine in Camino 2003080402 but crashed since 2003080502.

Here is a url that surely crash it:

In the interest of preventing any further onslaught of "me too" bugspam I think
we have enough examples of sites that are triggering this crash now ;)

The next step now is to wait for the fix to get checked in and a build to get
out with the fix to verify all links here work ok.
