When creating a listview without specifying a template (ok, not very real situation, but still....) you get an error
In this lines:
that.template = kendo.template(options.template ||
""
);
that.altTemplate = kendo.template(options.altTemplate || options.template);
The second line should be:
that.altTemplate = kendo.template(options.altTemplate || options.template ||
""
);
