I cannot see the cause of this error

I have stared at this for a while and cannot see the problemf in MiKoMH/AI/source/probabilistic-reasoning/slides/probdist.en.tex. I get errors

./probdist.en.tex:63: Illegal parameter number in definition of \iterate.
<to be read again> 
                   1
l.63 \end{frame}

./probdist.en.tex:63: Illegal parameter number in definition of \iterate.
<to be read again> 
                   1

./probdist.en.tex:63: Illegal parameter number in definition of \beamer@doifinframe.
<to be read again> 
                   1
l.63 \end{frame}

which goes away when I comment out line 38:

      \varseq{Xseq}1n{\comp{X}_{#1}}

But I cannot understand why.

and this messes up a lot of things, since it is a widely used import

Solved by adding [fragile] to \begin{frame}

For the Record: Actually, there was another problem: \ProbDist should have had [args=a but had [args=1 so it was not fit to be applied to a sequence.
