I'm trying to write a site file to crawl a bug list from a local
installation of bugzilla, and during my attempts I tickled a bug. The
main url is, believe it or not, something like this vile apparition:
http://bugzilla.localdomain/buglist.cgi?bug_status=NEW&bug_status=ASSIGNED&bug_status=REOPENED&email1=aspiers&emailtype1=substring&emailassigned_to1=1&email2=&emailtype2=substring&emailreporter2=1&bugidtype=include&bug_id=&changedin=&votes=&chfieldfrom=&chfieldto=Now&chfieldvalue=&short_desc=&short_desc_type=substring&long_desc=&long_desc_type=substring&bug_file_loc=&bug_file_loc_type=substring&field0-0-0=noop&type0-0-0=noop&value0-0-0=&newqueryname=&order=bugs.priority%2C%20bugs.priority%2C%20bugs.bug_severity
which resulted in the following mysterious errors:
print on closed filehandle Sitescooper::CacheSingleton::PID at
/nfs-home/adams/lib/perl5/Sitescooper/CacheSingleton.pm line 82.
print on closed filehandle Sitescooper::CacheSingleton::OUT at
/nfs-home/adams/lib/perl5/Sitescooper/CacheSingleton.pm line 97.
They turned out to be the result of an unchecked open() failing.
With this patch:

I'm not sure what to do about that though.
