I've run into some problems like this before when I was doing lots of
stuff inthe middle. Remember that the lua2C stack gets blown during
certain operations. I've found that almost everyplace I use "next"
from C, I end up making a lua_ref, doing some work, and then
dereferencing the lua_ref. Here is some psudo-code:

this_index = next(varname,nil);
this_index_ref = lua_ref(this_index);
while (there_are_more_values) {
  /* do some stuff with this_index */


  /* get next */
  this_index = next(varname,lua_getref(this_index_ref))
  this_index_ref = lua_ref(this_index)
}
