[Zope] Uh-oh, my Zope site is going down the toilet! (NameError in DT_Util.py)

Earlier I reported a problem with copy/pasting a DTML method.

Now I'm getting a NameError exception in DT_Util.py, line 337 (in eval). This 
appears to be either an acquisition problem, a security problem or a 
combiniation in conjunction with LoginManager.

(the traceback is at the bottom of this message)

Zope version: Zope 2.2.1 (binary release, python 1.5.2, win32-x86) 

Here's my layout 


  Strader (folder)
       DateRange  (External Method)
       Outbound  (folder)
          InTransit  (DTML Doc)
          ReportBanner (Dtml Method)
          Reports (DTML Doc)
          ReportForm (DTML Doc)
   acl_users (LoginManager)
acl_users (user folder)

ReportBanner and ReportForm both use <dtml-var "DateRange(value)[0]">

ReportBanner is called from InTransit, and it works. It works when authenticated 
via LoginManager or by the root acl_users folder 

When ReportForm is called from Reports, I get a NameError exception if 
authenticated solely via LoginManager. However when logged in on another 
machine, authenticated via Loginmanager, it works. I suspect that copy of the 
browser is also sending Basic Auth credentials, but I can't be sure.

Earlier today I reported that I couldn't copy/paste ReportBanner. It seems that 
this object, and ReportForm are owned by a user in LoginManager, though I 
don't know how that happened.. cookie exchange probably.

I'm wondering if there's something strange happening with LoginManager, 
ownership, acquisition and so on. It seems like I can't take ownership of these 
objects either, and the "make ownership implicit" button doesn't seem to have 
any effect.

So anyway, I'd expect an attributeError or a UnAuthenticated error, but 
NameError is unexpected and looks very suspicious to me. My customer has 
spent a *lot* of money on this project so far, and I'm worried that I have some 
strange bug running through the system now due to these  two unexpected 
problems (copy/paste and now nameerror) I can't think of a workaround for
