On the English Wikipedia, if math display preferences are set to MathML, this revision: https://en.wikipedia.org/w/index.php?title=Courant_minimax_principle&oldid=663685200 creates "[ebbdfa39] 2015-12-17 14:20:54: Fatal exception of type "MWException"". If math preferences are set to PNG, it displays correctly. See https://en.wikipedia.org/wiki/Wikipedia_talk:WikiProject_Mathematics#MWException_in_maths_expression for discussion. The issue is apparently cause by using \binom in a subscript, which is a workaround for the \substack that LaTeX users would normally use.
