I'd hazard a guess that, somewhere in the code, some snippet is calling Apache::Compress->handler (as a class method) which means that the string "Apache::Compress" is the first argument, not the Apache::Request object you expect.
Try... sub handler { my $r = shift; print STDERR "r is a " . (ref $r) . " and caller is a " . (join " ",caller()) .

This is the handler from Apache::Compress.pm: use strict; use Compress::Zlib 1.0; use Apache::File; use Apache::Constants qw(:common); use vars qw($VERSION); sub handler { my $r = shift; my $can_gzip = $r->header_in('Accept-Encoding') =~ /gzip/; # <---- line 14 my $filter = lc $r->dir_config('Filter') eq 'on'; #warn "can_gzip=$can_gzip, filter=$filter"; return DECLINED unless $can_gzip or $filter; ... } I have observed this more often on our solaris platform than on linux. Any ideas?
