134702 - MailNews segfaults during "download and sync"

Status: VERIFIED DUPLICATE of bug 134070

(SeaMonkey :: MailNews: Backend, defect)

Description

[basic]

UA: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.9+) Gecko/20020329

I often do a File->Offline->"Download and Sync Now..." when starting MailNews
and then start reading the messages even before all of them are downloaded.
Recently I've been seeing crashes (not sure if they were there before). Here are
some talkback ids:

TB4679591E
TB4679667Y
TB4703535X
TB4703668W

Not sure what is causing this. Might even be a dup.

Basic,
How many mesgs are you downloading? Are you checking the work offline
checkbox when download completes in download/sync now window?
I assume you were using imap mail account also.

Using commercial trunk 2002040108 on linux 2.2 this works for me
I tried downloading inbox of 100 mesgs (no work offline checkbox checked)
and I was able to read mesgs while they were downloading.

Tried another folder of 800+ mesgs (this time w/work offline checkbox
checked) and I was able to read mesgs while downloaded. I even
tried opening some of downloaded mesgs in a new window and it worked.

No crash for me.

here's the stack trace:

I don't know if there have been any recent linux event queue changes... I'll
seach bugzilla for the same stack trace.

sorry for not being clearer, I was reading newsgroup messages and downloading
news messages from news.mozilla.org

what skin are you using? There are a couple bugs with the same stack trace: bug
132597 and bug 134070 - one of them has a patch in it. Also, are you running on
a single cpu machine or dual-processor?

> How many mesgs are you downloading?
Sometimes alot and sometimes less, not sure if that has anything to do with it.
I can't always repro this bug, but I see it as often as once a day (sometimes more).

> Are you checking the work offline checkbox when download completes in 
> download/sync now window?
no "work offline"

> what skin are you using?
classic

hmm, guess they are related. I do use pop mail and had a "crash logging into pop
mail server" problem (sorry didn't get a talkback build back then) about a week
ago when I created a new pop mail account (seem to have disappeared now).

> Also, are you running on a single cpu machine or dual-processor?
single processor

Trying it with Newsgroups (no workoffline checkbox checked) in
the classic theme, I could not crash. Worked for me.

But I did see the exact same stack crash doing 2 different things:
 1) I clicked on secnews group. It asked me to download 500 headers
    I said yes. it asked me for my password, I clicked cancel and
    it crashed. TB4705372K
 2) I just subscribed to couple of mozilla newsgroups. I clicked on
    a newsgroup, got prompt to download 500, I said ok. I then clicked
    on another newsgroup, got the prompt to download 500, I said ok
    to 2nd newsgroup and it crashed TB4706073W

Both cases had same exact stack trace.

Don't think this is a offline bug..

For fun, you might try switching to the modern skin and see if the problem goes
away. 

Comment 8

[basic]

I'm wasn't sure where to file this so I file it in "offline". I'll try modern

Comment 9

crash with modern skin TB4708619M

one way I have found that will cause the crash (almost reliably) is to press the
spacebar again and again and again (to cause page down and go to the next new
message) while mailnews is doing the "download and sync" for the newsgroups.

that crash looks like the pop3 prompt one, and also involves a dialog getting
popped up (and, I guess, events getting processed on the wrong thread, or
something). The dialog is the "do you want to advance to the next folder" one.

Comment 11

[basic]

my guess is this is a likely dup of bug 134070 then

Comment 12

[grylchan]

Ok for now i'll mark as dupe of 134070.
Basic if you still see this bug after that other bug
is fixed, please reopen.

it's that bug, for sure.  Cropping up all over the place.
