The arms depicted are those of Sankt Radegund bei Graz, Styria, Austria, whose blazon is described in the German Wikipedia page as:
Very pretty, but unfortunately it has nothing to do with our Radegund, who was born somewhere in Thuringia in central Germany. Sankt Radegund bei Graz is actually named after a completely different Radegund, Radegund von Wellenberg (links to German text), who was fatally injured by wolves. Hence the wolf heads, presumably. What the bucket is for I cannot as yet find out.
