Issue with price format on Product Page (getPriceHtml)

I'm having troubles with the price formatting on a product page of a downloadable product. The format (as defined globally) should be EUR 15.23. It work's fine in the sidebars, category pag开发者_开发问答es, homepage and so on. Anyway, on the product page the price is shown wrong (without space): EUR15.23

catalog/product/view.phtml:

//calling once - price EUR15.23
<?php echo $this->getPriceHtml($_product, true); ?>

//calling twice - first price EUR15.23 second price EUR 15.23 (correct)
<?php echo $this->getPriceHtml($_product, true); ?> 

same problem when calling:

<?php echo $this->getChildHtml('product_type_data'); ?>

I think it has to do with the reloadPrice : function() JavaScript Code in downloadable/catalog/product/links.phtml

Anyone also had this problem? Actually I don't want to get through the JavaScript-Code and change something here as I do not want to change the core files.

Thanks!

Sure it isn't right solution, but if I got you right and it is always true that "first price EUR15.23 second price EUR 15.23 (correct)", then why not just

<?php $this->getPriceHtml($_product, true); // no output  ?> 
<?php echo $this->getPriceHtml($_product, true); // correct output ?>
