Status: VERIFIED FIXED

(MailNews Core :: Backend, defect)

Description

[Ralf Angeli]

Mozilla is crashing while opening an IMAP mailbox (MS Exchange). The crash
occurs right after entering the mailbox password. Note: I am using SSL with this
mail account.
The crash occured first in builds from 2001-10-17 (builds before that date are
not crashing).
Talkback ID of the crash using build 2001102008 on Linux (SuSE 7.1, kernel
2.4.10) is: TB36969911G

No dupes found. Marking NEW.

Related to bug 105904? (that also has the string "NS_ConvertUTF8toUCS2::Init").

I cannot reproduce this crash on 10-20-12-0.9.4 branch build for our internal MS 
Exchange 5.5 server. 
Are you using trunk build, can you reproduce this crash again on the latest 
build?

Comment 5

[Karen Huang]

Is this crash also occuring on your MS Exchange server WITHOUT SSL?
I tested on our Messaging server SSL is working without crash.
Since we don't have MS Exchange SSL setting internally, do you have test 
accounts for me to test? If yes, can you send the server/account info to me? 
Thanks.

The latest trunk build (2001102210) seems to work. I cannot see the crash
anymore either.

Comment 7

[Karen Huang]

Great! Thanks for the updates. Marking as WFM based on reporter's comments.

Comment 8

[Karen Huang]

Verified. Please reopen this bug if you see the crash again, thanks,

Comment 9

[Ralf Angeli]

Ooops, sorry, I got the crash again. :o(
First it was working fine, but then I deleted some mails and Mozilla crashed.
After that I could not open the mailbox anymore without crashing.
The talkback ID of the reproduced crash is TB37027942M.

Is this crash also occuring on your MS Exchange server WITHOUT SSL?

Comment 11

[Karen Huang]

I am still not getting the crash even after I deleted msgs from our Netscape 
Messaging IMAP SSL account.....

Comment 12

[Ralf Angeli]

Yes, I got the same crash without SSL. The crash occurs either while opening the
mailbox or randomly when you move around in your mailbox or delete some mails.
I am using a trunk build, maybe the problem does not exist in branch builds.

Maybe Alex is right and this is related to bug 105904, even if the reporter
there is just reporting a hang and not a crash.

Comment 13

[Karen Huang]

Thanks for checking.
Updating the summary a little bit and adding bug 105904 for this bug dependance 
based on reporter's comments.

[scottputterman]

cc'ing jag.  This looks similar to 105904.  Is this also your bug, jag?

Comment 15

[jag (Peter Annema)]

Yeah, that's mine.

I have two different approaches to fixing this, I need to go over them with
dbaron and scc.

Comment 16

[scottputterman]

reassigning to jag based on his last comments.

Comment 17

[jag (Peter Annema)]

This should be fixed. Please verify!

Comment 18

[Ralf Angeli]

I am using Mail/News (build 2001102521) for nearly a day now and haven't had a
crash. So the fix seems to be bulletproof. :o) Thanks for that.
I don't know if I, as a reporter, am entitled to mark the bug as verified, so
I'm leaving the status untouched.

Verified no crash for accessing MS Exchange mail account now.
Windows and Linux Build 11-15-06-trunk build.
