boftx was right and spotted the problem with argument passing to your printdirs sub. You also had a problem with the dereferencing syntax:
@($mydir->subdlist) should be @{$mydir->subdlist}
Also, while it's not an error, the check to see if the array is empty is redundant, the for loop wont run if there are zero elements in the array. So the sub could be rewritten as:
sub printdirs {
my ($mydir) = @_;
printdirs($_) for @{$mydir->subdlist};
print "Dir: ", $mydir->dirname, "\n";
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
