I wonder if this line (line 74 of the module source) has anything to do with it: 
sub new {
  my $that = shift;
  my $class = ref($that) || $that; #<-- (line 74)
# [snip]
  bless $self, $class;

}

I've never seen a class name determined that way before. ref($that) will return the type of reference if $that is a reference. That doesn't seem right, does it? I'm thinking maybe the module author meant to use a conditional operator there instead.
