Easy enough to reproduce:

http://duolingo.wikia.com/wiki/Template:Storeinfobox?oldid=32366

http://duolingo.wikia.com/wiki/Template:Storeinfobox?diff=prev&oldid=32332

http://communitytest.wikia.com/index.php?title=Template%3AInfoboxstuff&diff=29549&oldid=29548

Perhaps one of the times it happens is when the template doesn't output anything at all in the template namespace.

P.S. It might only happen with templates that weren't originally labelled as "infobox type".
