Hello,

In Mandrake's bugzilla is a bug posted for mc which I can't reproduce
myself. Someone here might want to take a look at it though:
http://qa.mandrakesoft.com/show_bug.cgi?id=12842

Basically it comes down to this:
<quote>
Keys : F9, Options, Configuration (no modification needed), F10. I can
continue
to use mc without problem. And the segfault appears only when I quit. No
segfault on quitting if I do not open Configuration box during the mc
session.
</quote>

This happens with the 4.6.0 in Mandrake 10.1 and with 4.6.1-pre3 in
current cooker. It happens with the utf8 patch applied, and without it.
It doesn't happen with the rpm from the mc website of last December, so
it seems to be a compile time probem (?).
There's a backtrace posted from gdb with the non-utf8 package:

gdb mc (no_utf8):
<Option, Configuration, quit>
Program received signal SIGSEGV, Segmentation fault.

If there is more info needed I can forward that, or you could mail the
reporter directly, I assume.
