jquerymobile large custom select list error on select

I have a page, which contains a select/options element. I am also using NativeMenu = false.

When the size of the select list is small enough for it to render all onscreen, there are no problems.

But, when the list is too long, and a ui dialog is required, I get the following error on selecting an item from the list

TypeError: fromPage.data(...) is undefined
fromPage.data( "mobile-page" )._trigger( "hide", null, { nextPage: toPage } );
jqueryMobile-1.3.2.js (line 4061)

After which, the original page is re-presented, but the Select element is no longer operational.

Is there anything obvious I am missing?

EDIT #1

I'm generating the selectbox with the following ASP.Net MVC code:

<div style="width:55%;float:left;" id="itemMenuArea">
    <select name="itemFilterMenu" id="itemFilterMenu" data-theme="c" data-corners="false" data-mini="true">
        <option value="-1">All Items</option>
        @foreach(var choice in (IEnumerable<SelectListItem>) ViewBag.EventList){
            <option value="@choice.Value">@choice.Text</option>
        }
    </select>
</div>

The output of that looks like this:

<div id="itemMenuArea" style="width:55%;float:left;">
    <div class="ui-select">
        <a href="#" role="button" id="itemFilterMenu-button" aria-haspopup="true" aria-owns="itemFilterMenu-menu" data-corners="false" data-shadow="true" data-iconshadow="true" data-wrapperels="span" data-icon="arrow-d" data-iconpos="right" data-theme="c" data-mini="true" class="ui-btn ui-shadow ui-mini ui-btn-icon-right ui-btn-up-c"><span class="ui-btn-inner"><span class="ui-btn-text"><span>All Items</span></span><span class="ui-icon ui-icon-arrow-d ui-icon-shadow">&nbsp;</span></span></a>

        <select data-mini="true" data-corners="false" data-theme="c" id="itemFilterMenu" name="itemFilterMenu" tabindex="-1">
            <option value="-1">All Items</option>

    </div>

EDIT #2

I tried again to build a jsFiddle, but the results are that it seems to work just fine in the fiddle.
