Are you using zope.sendmail's mail:queuedDelivery in the project? If
yes, upgrade to zope.sendmail 3.5.3, which will make it into Zope
2.12.18. Earlier versions registered an atexit handler that wasn't
compatible with Python 2.5+. The bug was only fixed in later versions
of zope.sendmail but not backported to the 3.5 stable branch.

Otherwise what operating system are you running on? On Windows you
need to hit Ctrl-C twice IIRC.

Do you have any custom software that registers system exit or signal handlers?
