Is this doit-1 function actually used somewhere in your init.el or in
your .emacs?  If it is, can you show the code that uses it?

Can you turn on debug-on-error and show the Lisp backtrace for these
messages?  Each time a backtrace appears, type "C-]" to get out of the
debugger and continue to the next error.
