"Invalid template" error when activating edit toolbar

Given a polygon graphic created with the draw toolbar, I am activating the edit toolbar to modify it.

// geoObj.polyObject is the polygon graphic
this.editToolbar = new esri.toolbars.Edit(this.map);
this.editToolbar.activate(esri.toolbars.Edit.EDIT_VERTICES, geoObj.polyObject);

This is just like in the code samples, but I'm getting the following dojo error (in chrome and firefox):
Uncaught Error: Invalid template: <table class="dijit dijitMenu dijitMenuPassive dijitReset dijitMenuTable" role="menu" tabIndex="${tabIndex}"
    data-dojo-attach-event="onkeypress:_onKeyPress" cellspacing="0">
 <tbody class="dijitReset" data-dojo-attach-point="containerNode"></tbody>

Googling tells me that dojo is probably throwing this error due to whitespace at the end of the dijit template.  But since it's all done from deep in the (minified) arcGIS js library I'm not able to fiddle with it to confirm the cause.

I've tried catching this error with a try/catch block, and the vertex handles then show up, and can be used to edit the shape, but when I deactivate the toolbar later, the vertex handles do not disappear, which I suspect is because the vertex editor wasn't properly set up, due to this error.

Any suggestions?
