Unfilled %s in some calendar entrys

[sourceforge807]

Hi @ all

i used this wunderfull projekt and it is really nice.

but at the moment i had a problem. When i used the system language “de” some calendar events show “%s”. When i switch to “en” or “fr” it shows the right number. The following pictures shows what i mean:
de:

en:

fr:

this is the modul config in the config file:

		{
			module: "calendar",
			header: "Gesetzliche Feiertage",
			position: "top_left",
			config: {
				maximumEntries : 5,
				colored: true,
				calendars: [
					{
						color: "#f0ffff",
						symbol: "calendar-check",
						url: "webcal://abo.kleiner-kalender.de/ical/c48-feiertage-in-deutschland.ics"
					}
				]
			}
		},
