rim:loadingScreen with animated GIF foregroundImage causes Application Resource Monitor on BBOS 7.1 to shut down application after ~30 minutes in background.

Not producible if:

rim:loadingScreen is omitted; or
non-animated images are used instead.

Sample config.xml:

<?xml version="1.0" encoding="UTF-8"?>

<widget xmlns="http://www.w3.org/ns/widgets"
    xmlns:rim="http://www.blackberry.com/ns/widgets"
    version="1.0.0.0"
    id="gif"
    xml:lang="en">

<name>GIF</name>
<author>Oros</author>

<content src="index.html"/>
<access uri="*" subdomains="true" />

<rim:cache disableAllCache="true" />

<rim:loadingScreen foregroundImage="loading.gif" onLocalPageLoad="true"> 
    <rim:transitionEffect type="fadeOut"/> 
</rim:loadingScreen>

</widget>

Sample index.html

<!DOCTYPE html>
<html>
<body>
    <div id="loaded"></div>
    <script type="text/javascript">
        /*global window, document, console */

        'use strict';

        function onDOMContentLoaded() {
            window.removeEventListener('DOMContentLoaded', onDOMContentLoaded, false);
            document.querySelector('#loaded').innerHTML = 'Loaded.';
        }

        window.addEventListener('DOMContentLoaded', onDOMContentLoaded, false);
    </script>
</body>
</html>

Allowing the application to start, you will see the loading icon, then the content of the screen (i.e. 'Loaded.') Pressing the End button will minimize the application and letting it run produces the error.
