The script has an id and there's nothing wrong with the filename

two results it somehow messes with the Lua stack (or something like
that) and process_getScriptId() in nse_main.cc results in script abortion.


Great work in tracking this down, Jah!  I'm glad that Patrick has
applied your patch to prevent showSMTPVersion from returning multiple
values.  But we should fix the underlying problem.  A script returning
multiple values should not silently cause mysterious corruption
elsewhere in NSE.  Anyone have ideas as to the best way to fix this?
