[plt-scheme] Embedded images in planet packages

I can't seem to install a planet package that has an image embedded in 
the source code (via Insert Image).  When I try to inject the package, I 
get:

write: cannot marshal constant that is embedded in compiled code: 
#(struct:object:image% ...)

Any idea on how to work around this?  Should this be considered a bug?
