The problem is likely there. In a nutshell, some helm code seems to be incompatible with pre-redisplay-function (probably something related to region or some such, but that's just a guess at this time). > With this version of emacs (24.3.91) it is usable because I let-bounded > `pre-redisplay-function' to nil, but the message is still here, with > Emacs-24.4.50, quitting is nearly impossible, and the message contain > byte-code. > With emacs-24.3 it is working normally. > This is relatively recent. > > This is happening when hitting C-g on a helm command that use an async > process, but only on the helm-locate command. > > Another strange thing is when hitting C-g on a long helm-grep process, > C-g works normally but return "Emacs-lisp:" in the minibuffer when done. > > To reproduce:(best from emacs-24.4.50) See above: please investigate helm code some more, it shouldn't be necessary for us to install helm to find the offending code. You are the helm maintainer, so you are in a much better position to find the offending code there. Once the code is found, please show it here, and we can take it from there, perhaps asking you a few questions. Thank you.
