[Zope] "DeprecationWarning" breaks the socket connection?

[iap@y2fun.com]

I use export/import to transfer a ZClass product from a Zope-2.3
installation to
a Zope-2.4 one. There is "DeprecationWarning" dumped to the console.
And the connection between zope and the browser is then broken.
Is there any way to suppress the warining? or any workaround?

Thanks for any suggestion.

Iap, Singuan
