[esther]

Karen, I think you have a bug on this, can you find the dup?

Comment 3

[selmer (gone)]

Please clear the status whiteboard if this is NOT a dup.  Thx.

Comment 4

[Karen Huang]

Is this crash occurring when quit from the mail window or quit from the app?
There was bug 7799 logged.......clear b3 need info

Comment 5

[Scott MacGregor]

I haven't been able to reproduce this on my Mac yet.

Comment 6

[Karen Huang]

I haven't been able to reproduce this on today's 09-14-08-M18 Mac commercial 
build, either.

Comment 7

[Mike Pinkerton (not reading bugmail)]

Karen, your stack is bug 52836 "Crash every time browser exits".

Comment 11

[selmer (gone)]

We need to be able to repro this before we start digging for solutions.

Comment 12

[Suresh]

I cannot reproduce this bug. But I can consistently reproduce the general crash 
- 52836. I don't see any IMAP code in that Stack trace. 

I tested on today's commercial debug build on Mac OS 9.0.

Comment 13

[selmer (gone)]

Suresh, any reason you didn't close this WFM?

Comment 14

[Suresh]

Pinkerton, are you still seeing this crash? If not, can you close this as WFM?
Thanks!!

Comment 15

[Mike Pinkerton (not reading bugmail)]

i can't say "yea" or "nay" on if i still see this, because i can't get a working 
mac build reliably.

My guess is that this still lurks, unless someone on the mail team thinks they 
fixed it.

Comment 16

[selmer (gone)]

Please clear whiteboard if this becomes interesting again.  nsbeta3-

Comment 17

[Mike Pinkerton (not reading bugmail)]

the 9/27/00 11am branch bits crash every time at shutdown with this stacktrace
for me on mac.

- launch app
- cmd-2 to open mail
- cmd-q to quit.

boom. removing nsbeta3- for re-triage, nominating for rtm, bumping priority to
PDT sees it.

Comment 18

[selmer (gone)]

pink, can you help one of us reproduce this so we have a chance of figuring it 
out?  Thx.

Comment 19

[Scott MacGregor]

arggh...I'm still trying to get this to happen but just can't trigger it.

Comment 20

[Mike Pinkerton (not reading bugmail)]

i see this about once a week on my mac running on the branch. it's not
reproducable, but it does happen with frequency.

Comment 21

[Mike Pinkerton (not reading bugmail)]

forgot to mention that i crashed here just this morning (build 10/5/00, 10am,
branch, modern skin).

Comment 22

[Scott MacGregor]

I wonder if this is caused by 58657....

Comment 23

[Scott MacGregor]

the potential fix for this is in 58657. I'm not sure if it fixes it fore sure
though. I haven't run into this problem on my mac in a while to begin with.

Comment 24

[Scott MacGregor]

with a debug build from yesterday, I started up 5 times and shut down 5 times
after using imap. It came out clean all 5 times. This was without my suggested
fix for 58567. I wonder if this has gone away? rtm- for now...

Comment 25

[David :Bienvenu]

nominating for next release, if not already fixed.

Comment 26

[scottputterman]

Is anyone able to reproduce this with a current build?

Comment 27

[Karen Huang]

Verified on Mac 01-02-08-Mtrunk build.
The crash is not occurring anymore. 
Marking as fixed in order to close this bug.

Comment 28

[Karen Huang]

verified.
