149605 - crash opening mail window after new account created

Status: VERIFIED WORKSFORME

(MailNews Core :: Backend, defect)

Description

[Chris Waterson]

I've just created a new profile on OS/X, and crashed immediately after 
completing the account setup dialog. Now, I crash whenever I try to open 
the mail window.

It looks like mEncoder is null at about line 237 of nsCollation.cpp. There's 
some RDF on the stack, so I'll look at it a little bit to try to figure out what's 
going on.

Here's the stack:

I get a few assertions before the crash, too:

WARNING: NS_ENSURE_TRUE(NS_SUCCEEDED(rv)) failed, file ../../../../

Comment 2

[Chris Waterson]

It looks like the charset that's being passed in here is the empty string: 
the charset converter manager is returning `success' even though it never 
gives us back a unicode encoder (probably a bug, but no the real bug). 
I18n guys, should we file something on that?

Comment 3

[nhottanscp]

nsCharsetConverterManager::GetCharsetAtom
nsCharsetConverterManager::GetUnicodeDecoder

Those returns success even the input is an empty string. I think this is wrong.
I will talk to Frank about this.

Comment 4

[nhottanscp]

Correction to my last comment, 
nsCharsetConverterManager::GetUnicodeDecoder returns an error
NS_ERROR_UCONV_NOCONV. The same for nsCharsetConverterManager::GetUnicodeEncoder.

Comment 5

[nhottanscp]

225     nsCOMPtr <nsIAtom>  charsetAtom;
226     res =
mCharsetConverterManager->GetCharsetAtom(PromiseFlatString(aCharset).get(),
getter_AddRefs(charsetAtom));
227     if (NS_SUCCEEDED(res)) {
228       if (charsetAtom != mEncoderCharsetAtom) {
229         mEncoderCharsetAtom = charsetAtom;
230         res =
mCharsetConverterManager->GetUnicodeEncoder(mEncoderCharsetAtom,
getter_AddRefs(mEncoder));
231       }

If GetCharsetAtom returns success even the charset is empty and the following
atom comparison is equal then mEncoder can be null. 
waterson, is that the case of your crash?

Chris, are you still seeing this?

Comment 7

[[e-mail] (gone - use [e-mail] instead)]

I don't see this on 2002-09-26-08, Mac OS X 10.1.5.  Please reopen if you see
this again, thanks.

Comment 8

[[e-mail] (gone - use [e-mail] instead)]

I don't see this.  If anybody else does, please either reopen or just file a new
bug.  Thanks.  Build 2002-09-27-08, Mac OS X 10.1.5.
