[Bug-gnubg] Using the ru_RU.KOI8-R locale causes a segfault

[Russ Allbery]

I got, and confirmed, a report from a Debian user that starting gnubg in
the ru_RU.KOI8-R locale causes a segfault after clicking on New Game.
This doesn't seem to affect other locales (I tried German).  It seems
suspiciously like a memory clobber.  The backtrace isn't particularly
useful:

(gdb) bt
#0  0xb7ee1335 in ?? ()
   from /usr/lib/gtk-2.0/2.4.0/loaders/libpixbufloader-xpm.so
#1  0x00000000 in ?? ()

I'm happy to help with further debugging, but am not sure the best way to
go about doing so.  valgrind reports an access to memory that isn't on the
stack or malloc'd (after bumping the valgrind error limit -- gnubg
produces a *ton* of valgrind errors, many of which in its dependent
libraries) deep inside the XPM loader, and I couldn't see anything
obviously wrong with the call site.
