Problem with adding entries with periods in HList?

Can anyone clue me into why "line2" in the following cannot be added
as a line in a Tk HList? I get:

parent element "This . is . another . line" does not exist at
/usr/local/lib/perl5/site_perl/5.6.1/i686-linux/Tk.pm line 228.

It seems like any string containing a "." cannot
be added as an entry? But I'm unclear as to why that is. I could add
it by specifying the path as '' instead of $line2, but then the line
is
not selectable.

Thanks in advance.

$hlist->add( $line1, -text => $line1 );
$hlist->add( $line2, -text => $line2 );

From the Tk::HList pod:

Name: separator
Class: Separator
Switch: -separator

Specifies the character to used as the separator character
when intepreting the path-names of list entries. By default
the character "." is used.
