Not sure where this one belongs, I believe that Aaron worked on Type ahead Find,
so I will cc him. Aaron, please feel free to change this if it belongs somewhere
else.

This signature is showing up as a topcrash on the Trunk and in M1.2 Beta on
Windows and Linux. (The only user comments are at the bottom.)

my guess is that treeItem is null.

treeItem(do_QueryInterface(startingContainer));

Thanks for the temporary fix.

I do presshell -> prescontext -> docshell.

I do a null check on the presshell and prescontext, but I wasn't checking the
docshell.

Does anyone know when a presshell and prescontext can still be alive, but the
docshell isn't?

Perhaps the simple adding of this null check is the right fix after all.

According to jkeiser this should not be happening.

There should never be a case where there is a presshell without a docshell.

Right?

Both user comments say this is something related to "find again". I think this
is the same as bug 177039, but I cannot get a test case where it will crash for
me, or hit the assertion added by timeless.

I think this must have been fixed by one of the changes to the
nsTypeAheadFind::FindNext impl along the way.

I raised bug 176472 with a test case that caused this crash.  Have you tried
that as your test case?

I also did a retest with a nightly build showing it was fixed, at least for my
test case, details in the bug comments.

I'll reiterate Ian's comment: I got this crash by:

- visit page
- do typeaheadfind search
- visit other page
- type F3

I *think* it only crashed if the second page didn't contain the string we
searched for initially, but I can't say that's true. It's fixed by this band-aid
for now, anyway.

I'm not sure it's the band-aid that fixed it. I can't even get it to assert
there (in a debug build). It might have been changes to our "find next" handling
code that fixed this.

Aha, I have it asserting now.

1. Go to www.generalcoffee.com
2. type "soft" <Enter>
3. type F3

Asserts or crashes depending on whteher you have the "band-aid" fix for this bug.

Could you comment that here, the typeAheadPresShell is not really the
typeAheadPresShell (we get the real shell later on and re-assign into this
var)...
