[Zope] Zope with w3m

[Heimo Laukkanen]

Zope seems to have problems with w3m -- the text browser. Atleast I get 
following tracebacks all the time:

  Zope Error
       Zope has encountered an error while publishing this resource.
       Error Type: ValueError
       Error Value: invalid literal for float(): =1.0
       <!--

Any ideas where to find more info?
