"External program failed to return required headers"

I am trying to use SWISH-E (I've tried both 2.2.3 and 2.4.0  pr1)  to 
spider our website.  Following directions in the documentation, I set up 
a basic swish.conf and spider.conf, and my indexing run always bombs 
with the message:

err: External program failed to return required headers Path-Name: & 

I found what appeared to be an identical problem report in the list 
archives from last April (<>), but 
didn't see a definitive solution posted there.  None of the suggestions 
offered there affect the problem here.

I took the liberty of inserting a line into to print out the 
headers, and every document it reports on does have Path-Name and 
Content-Length headers, which makes me suspect the problem is either 
with swish-e itself or in the interaction between and swish-e.

I've tried this against multiple web sites.  The number of files scanned 
before the indexing run dies varies from site to site, but is consistent 
on each site.  FWIW, I'm running swish-e under RedHat 8.0 with Perl 
5.8.0 (and, if I'm reading things correctly, LWP 5.65).

TIA for any help or suggestions.
