I don't know.  I think this is a general debugger issue and not
specific to Apache::DB.  Here's some test code that elicits the
problem:

#!/usr/bin/perl

my $s = <<EOF;
  package A;

#line 1 foofile
  sub foo {
    for (1..5) {
      print "Ni! \$_\n";
    }
  }
EOF

eval $s;
die $@ if $@;

my $subid = 'A::foo';
&$subid();

At least under perl 5.6.0, if I leave the #line directive in there
then the debugger doesn't display the statements when I enter foo();
if I remove it, everything works.
