[Zope] getSlice error in wiki folder with many objects?

[Troy Farrell]

My knowledge of DTML may be a bit rusty, but from what I see, the 
rendering of 'manage_options' is trying to execute this:

URL[-(_.len(action)):]==action or URL[-17:]=='/manage_workspace' and 
_['sequence-start'])

which, since it is in DTML, calls careful_getslice.  At line 174[1], 
careful_getslice executes this:

         v=seq[indexes[0]:]

where seq is the sequence it is trying to slice.  In our case, I bet 
that seq is the URL from above.  It looks to me like the URL above is 
not a string, or at least doesn't have a __get_slice__ method. 
Unfortunately, I don't know why this would be the case...

One thing that might help:  create a dtml method in a folder above this 
one with this one line in it:

<dtml-var REQUEST>

Then visit http://server/folderparent/foldernotworking/dtmlrequest and 
see what it tells you.  Is URL a string (I hope so...)
