	You can added .mgc, but extension is automatically added by rplfile.

	In a first time, you can replace rplfile by file (rplfile is a packaged
file to provide this utility on non POSIX systems).

	Maybe you should analyze coredump to find faulty system. I think there
is a bug womewhere in file. If you can open an ssh access to your
workstation, I could investigate. I'm unable to reproduce this bug.
