Problem with GTKLabel on Win98

Hi,
When I call GTKLabel() without any arguments I get an error message: "This 
program has performed an illegal operation" from Windows.

My code:
$label = &new GTKLabel();
$label->set_text("Text");
$label->show();

When I do it like this:
$label = &new GTKLabel("Text");
$label->show();

Or like this:

$label = &new GTKLabel("text");
$label->set_text("Text2");
$label->show();

I do not get any errors.
This did not happen with V0.0.4.

A bug perhaps??

Thanks,
David
