Script crashing when try and send an email from within a server socket handler.

System is GST 3.1 on Linux CentOS 5.2 64 bit.

To reproduce...
Set up a client and server as per...
http://sblinn.jottit.com/gnu_smalltalk_netclients-based_echo_server

At http://smalltalk.gnu.org/blog/swoolerton/mail-scripting-0 there is a class called SMTPHelper.

To see the fault, set the server atResponse method to something like this...

respondTo: aRequest [
 | session sessionSocket msg smtpHelper |
   "sending an email from the respondTo method crashes"
   smtpHelper := SMTPHelper new.
   SMTPHelper smtpHost: 'myMailHost'.
   smtpHelper sendEmailMsg: msg from: fromEmailAddr to:  toEmailAddr subject: 'Test'.
]
