[Zope] Virtual Host breaks IssueTracker?

[Matthew Wilbert]

I have IssueTracker (v.49b) installed in the root folder /help.
I have a VirtualHostMonster set up to map a second host name "help" to
/help. (using the
Mappings tab)  This is running under Zope 2.6.1b.

If I try to access IssueTracker through the normal url with a /help at
the end, it works fine.

If I try to access it through the mapped URL, it works, in the sense the
the IssueTracker home page comes up when I use the help url, but if I try
to look at an actual issue, I get the traceback at the end of this
message.

Is it a known thing that using virtual hosts breaks some products?  Is
there a standard workaround?

Thanks,

Matt Wilbert
