I can not reporduce this in my developement version (slightly different
that revision 580).  Could you try your example enabling Lisp 
debugger: 

)lisp (si::use-fast-links nil)
)set break break

Then try the drawing commands.  Insted of message you should see

BOOT>>

prompt.  Type :bt at the prompt.  Do this in a terminal which
has at least few hundreds lines of scrollback or use utility like
script to capture output.  You should see the chain of calls
which resulted in error -- this should indicate in which function
the error happended and how we got there.

To get out of debugger type '(quit)' -- that is call Lisp function
quit.
