[Zope-CMF] Be more Explicit about Problems/Exceptions was Erratci behaviour

[Zopista]

Just got this on my clients site this morning

> What version of ZOPE are you running?  2.5.1
> What version of CMF are you running? 1.2
> What CMF Products do you have installed? Plone, CMFCalendar, CMFCollector,
CMFWeblog, CMFWiki
> Do you see any pattern in whats causing this?  Nope
> Is the Python Script inside Filesystem Directory View? Yes, so fixed by
altering the script.
> if so does it have the context parameter defined? Yes

I quickly threw the context bit in question inside a try except which doesnt
solve the problem, but it means the site will work. I can reproduce this on
demand by deleting the altered script, I can have a look further tonight but
cant while the site is being used....
