+	Fix bug 623:
+	* commands2.el (kom-set-unread): Delete conf-stat from cache
+	before prompting. Fixed error handling.
+
+	Better handling of minibuffer reading:
 	* completing-read.el (lyskom-read-conf): Don't call
 	lyskom-with-lyskom-minibuffer since it's integrated in
 	lyskom-completing-read now.
