Issue when using the arrow keys (up/down) on dropdownlist

I have an issue in Firebug  when navigating with on a dropdownlist :
TypeError: d is undefined

_hideBusy(e=Object { originalEvent=Event keypress, type="keypress", timeStamp=167927338, more...})kendo.....min.js (line 16)

This happens only on Firefox (23.0.1) and not on Chrome.

Write something into the input field then press TAB and after that press the down arrow.
Any  ideas?

Hello Sergiu,

Thank you for providing the jsFiddle. I was able to reproduce the error and have logged it in our system for further investigation. We will fix it for one of the next internal builds. I have also updated your Telerik points for the bug report.
