I had this issue myself a week ago when I finally upgraded from 5.0 to 
5.1, and it took a bit of digging in the manual to figure out why it was 
dying. Would it be worthwhile to change the error message to include an 
explanation of the likely cause? Even if it were just a reference to a 
manual page, or something implying that an internal Lua function was 
being incorrectly called from C, that would prevent confusion (and 
wasted time, either my time digging through the manual, or the time of 
folks on the list answering questions that wouldn't need to be asked).

Just a thought,
