Problem with \type in captions

[Nikolai Weibull <mailing-lists.context-users@rawuncut.elitemail.org>]

\starttext
\placefigure
  {\type{0|}}
  {}
\stoptext

gives me

! Argument of \next has an extra }.
<inserted text>
                \par
<to be read again>
                   }
<argument> ...p {\strutdepth }\begstrut \type {0|}
                                                  \endstrut \endgraf
\doattributes ...sname #1#2\@EA \endcsname \fi {#4
                                                  }\dostopattributes
\putcompletecaption ...trut #3\endstrut \endgraf }
                                                  \fi \dostopattributes

l.4   {}

Remove the 0 and it works fine.  Is there a quick fix?,
