Strange issue with 4.1.1

Hi,
When using the plugin with 4.1.1 and some random “default” theme, a sort of “artefact” can be observed – adding additional unformatted code as HTML text.
For example :
” list=”y” autoplay=”y” loop=”n” pn=”n” stop=”n” images=”true” vol=”50″ dload=”false” pos=”rel-L” shuffle=”” pick=”” height=”92px” style=”nolistbutton”]

There is a shoutcast server added via a shortcode + some customization to the plugin itself.
The “trailing” data is part of the config, i.e. the quoted “vol=50” is part of the configuration.
A basic WordPress install + latest version of the jPlayer plugin can lead to the code.
Tested with different theme, same result
