Your problem is unrelated to \typesetbuffer and can be reproduced with 
the following example:

\definefontfamily[mainface][rm][TeX Gyre Pagella]

\starttext

\setupbodyfont[mainface, 17pt]

\input zapf

\stoptext


There are two solutions for this:

1. Use 17.3pt as fontsize because this is one of the predefined sizes.

2. Add \definebodyfont[17pt] at the begin of your document (should
    normally done by context itself when you use a undefined font size).
