The documentation here says: COLLECTION can be a list of strings, an alist, an obarray or a hash table. So using a vector isn't really supported, but works in some instances by chance. > On the other hand, executing > (completing-read "Test: " [1 2 3]) > and then pressing shows the error `(error "Bad data in guts of obarray")` It interprets all vectors as obarrays, and an obarray is just a vector of symbols. But numbers aren't symbols, which is what it's complaining about. We could make `completing-read' iterate over all the elements in the vector to see whether it's valid, and signal an error earlier, but it would make common usages slower. So I don't think there's an error in Emacs here -- feeding a (non-obarray) vector to `completing-read' is not supported, and is an error in the code that does it. So I'm closing this bug report. -- (domestic pets only, the antidote for overdose, milk.) bloggy blog: http://lars.ingebrigtsen.no
