Your solution doesn't seems to work, I still don't see a caption 
anywhere when using location=rightmargin. When I inserted your fix I 
stumbled upon the fact that there is \def\locatebcaptionbox below 
\def\locatefloatbox. You provided a fix for \locatefloatbox, but 
shouldn't it be for \locatecaptionbox? I have no clues about the 
internals of ConTeXt, but I tried the following:

\def\locatecaptionbox
    {\alignstrutmode\zerocount
 
\doifnotcommon{\floatcaptionparameter\c!location}{\v!outermargin,\v!innermargin,\v!leftmargin,\v!rightmargin}
       {\shiftalignedline
          {\floatcaptionparameter\c!leftmargin 
}{\floatcaptionparameter\c!rightmargin}%
 
{\floatcaptionparameter\c!innermargin}{\floatcaptionparameter\c!outermargin}}%
     \alignedline{\floatparameter\c!location}\v!middle}

Note that I just translated your fix to \locatecaptionbox. At least it 
didn't throw an error!

My attempt at understanding that explanation: The caption is placed to 
the right of aligned line (because it is supposed to got into the 
margin?), and for all things that are placed that way, 
\everyrightofalignedline is called. And that macro replaces the caption 
with a skip, but should instead skip across the margin skip and then 
place the caption?
