[Zope] Import Error 'PTKDemo' - but *no* PTKDemo objects around..

[Tony McDonald]

Hi all,
I'm having a nightmare here.

I have a Zope 2.2 (src, solaris) installation that I built from 
scratch. Then, because *it would not* import an exported folder from 
a 2.1.6 installation I had to use the Data.fs from the 2.1.6 
installation and strip out everything other than the folder I was 
interested in.

Things seemed to be ok, but I found a nasty error I can't get around.

I wanted to use the 'advanced' tab on a ZSQL method and immediately 
got this traceback. This happens on *any* ZSQL method. I use the 
ZMySQL database adaptor.

I've also tried this with Zope 2.2.1b1 and get the same result.

Any thoughts would be appreciated here, I'm out of ideas.
