It is not crashing (because of a programming error), but it is
failing (due to erroneous input). The error message is not the
most explicit one, but it gives a hint: something expect a stencil,
whereas it is given a list of stencils.

As Reinhold explained, the problem here is that you try to apply
a markup command, \fontsize, on a list of markup, whereas it accepts
a single markup. Thus you can write:
  \fontsize #-2 \column { \line { bla } \line { bli } }
because \column {...} is a single markup, but you cannot write:
  \fontsize #-2 { \line { bla } \line { bli } }
because { \line { bla } \line { bli } } is a list of markups (two
line markups).

The solution has been provided by Reinhold: write a \fontsize-line
markup-list command.
