I've found a repeatable way to get it recognized after issuing the command only one. I have to uncheck the wireless enable box after issuing 'sudo iwlist wlan0 scan essid <hidden_ssid>' and then recheck it. Apparently, just issuing the command does not cause the applet to rescan afterward, but unchecking / rechecking enable does. Then it will popup the kde wallet, as well as list it in the wifi list.
I have another bug that the popup does not resize automatically, so multiple wireless listings do not appear. The fix is to click on the collapse / expand button just left of the word "wireless" in the applet. This resizes it so I can see all my wifis.
