Comment (by neteler):

 Unfortunately I don't know how to debug tcl. but you can easily replicate
 it with Spearfish:

 {{{
 GRASS 6.3.svn (spearfish60):~ > nviz point=archsites
 Vector file archsites loaded with 25 points.
 curr = 1.0
 curr = 1.0
 curr = nan
 Error in startup script: can't use non-numeric floating-point value as
 operand of "*"
     while executing
 "expr int($curr * 1)"
     (procedure "Nv_mkFloatScale" line 17)
     invoked from within
 "Nv_mkFloatScale $Nv_(HEIGHT_SLIDER) v height $max $min $val update_height
 1"
 ...
 }}}
