I'm trying to download a wordpress website. For like 99% of the pages it copies
fine.

A couple of the pages (all archive pages for a particular taxonomy/post type)
won't come down (but some of that taxonomy/post type archive pages will). I
can't figure out the difference between the two, but it seems which do and
which don't is consistent.

Anyway the error I'm getting is: 

14:11:48 Error:  "Error when decompressing" (-1) at link
www.csun.edu/catalog/academics/cas/programs (from
www.csun.edu/catalog/academics/cas/overview/)

It also seems to treat the ones that work and the ones that don't differently
as far as the file systems go.

If it works it'll be term/programs/index.html if it doesn't it'll be
term/programs.html . Since all the pages are based off the same template they
should, in theory, be the same except for some of the body content. I've
looked at the debug and I can't find any difference between the requests.

Any tips on troubleshooting this?
