mc randomly segfaults after opening a file to edit (backtrace)

[Frédéric L. W. Meunier <lists2006 pervalidus net>]

Is this a bug ? It happens sometimes after closing a file I opened to 
edit. I don't need to change its contents to make it happen.

This is with latest CVS (not git).

Program terminated with signal 11, Segmentation fault.
