there should be a \normalexpanded in here:

\def\externalfigurereplacement#1#2#3%
{\setupcolors
[\c!state=\v!local]%
\normalexpanded{\localframed
[\??ef]
[\c!width=\figurewidth,
\c!height=\figureheight,
\c!background=\v!color,
\c!backgroundcolor=missingfigurecolor,
\c!frame=\@@efframe]}% we need to expand this in order to prevent
a loop
{\tt\tfxx \nohyphens
name:  \expanded{\verbatimstring{#1}}\\%
file:  \expanded{\verbatimstring{#2}}\\%
state: \expanded{\verbatimstring{#3}}}}
