Here's an example screenshot of the way Imp displays an event using the non-filled "%x" placeholder.

Using the current stable versions (Kronolith 4.2.23, Imp 6.2.21, Horde 5.2.17), there seems to be a problem when Imp displays a message with an invitation to a recurring event. In the event preview, there is a printf placeholder "%x" that is not filled. The attached ICS file contains an example of such an event. Please note that the problem only occurs when the event is displayed by Imp as part of an email with an invitation to participate in an event. There is no problem in importing and displaying the event in Kronolith.
