I think that Eli is plain right. Moreover, Thierry, the maintainer of Helm
never had any problems such as mines with Helm and locate. On Windows, the set
of programs is different, and Eli tells pratical constraints are as well quite
different.

So, this clearly seems to be Win32-only, reason why, maybe, there are so few,
or I'm the only one, reports of this.

FWIW, I currently regard Emacs 24.2.93 (from file
emacs-24-r111307-20130227-w32-i386.zip) as being as good as the Emacs 24.2.91
I've been using for weeks.

I (think we can) trust this version to have fixed problems introduced in
24.2.92 and first versions of 24.2.93.

Best regards,
  Seb
