User Agent: Mozilla/5.0 (Windows NT 6.0; rv:8.0a2) Gecko/20110903 SeaMonkey/2.5a2
Build ID: 20110903013026

Steps to reproduce:

I am using Windows Vista.

Send an email using SMTP and browse certain SSL/TLS sites at the same time.

Websites that cause SeaMonkey to stop responding:

Websites that do NOT cause SeaMonkey to stop responding:

My SMTP settings are as follows:
Server name:
Port: 25
Connection security: STARTTLS
Authentication method: Normal password
User Name:

I can confirm that this behaviour is not recent because I had the same problems with 2.1, 2.2, 2.3 (I am now using 2.5 aurora).

I originally posted this on MozillaZine before here:

Actual results:

SeaMonkey stopped responding. Looking at the network traffic through Windows Task Manager revealed that when the program stopped responding the network traffic stopped altogether.
Please try running with disabled addons.
We need a stacktrace with debug symbols but i don't know the symbol server address for SM...

I tried running with addons disabled and I still got the same problem. On a side note, also causes is to stop responding.

I also don't get a crash reporting window either; it just hangs until I end it no matter how long I leave it for.

Actually, forget what I said about There was something on that caused it to crash once, but it mustn't have been cached. Visiting does not cause it to crash during send.

I did a stacktrace using WinDbg (attached) using the instructions from

This was done on a new profile and the same results occurred.
There are a few more instructions that you missed under "After the crash or hang"

I have done another debug using those instructions. Sorry, I didn't realise I'd missed those, thanks for letting me know. :-)
Is that a deadlock (0% CPU) or a loop (100% CPU for one CPI core) ?

It is a deadlock.

Just an update: somebody on the topic at MozillaZine has confirmed that the bug can be reproduced on Apple OSX.

Also, I can confirm that it crashes on Debian GNU/Linux. So the bug is cross-platform.

In addition, it also appears to crash on ALL SSL websites now, including, YouTube, Mozilla, Wikimedia.

I only just realised one detail that I forgot to add in the original post:
Sending mail using my other provider (ISP, no SSL) works fine, no crash. That was the reason why I suspected it was due to the SSL being used in multiple places, or something up with the implementation.

Is this still reproducible with 2.8?

No, I could not reproduce this in SeaMonkey 2.8. I've marked the status as resolved. Thanks for everyone's help anyway. :)
