crash in tabcompleting

[Mikael Magnusson <mikachu@gmail.com>]

I'm using latest cvs (as of 20th march) and I'm getting segfaults when
i tabcomplete some files with utf-8 names. I'm not running in a UTF-8
locale though, and I think this worked earlier. I have in one
directory two files called
"大å¡\232æ\204\233 - 大好ã\201\215ã\201\237ã\202\231ã\202\210ã\200\202.avi"
and
"大å¡\232æ\204\233 - é\207\221é­\232è\212±ç\201«.mpg"
(listed with ls --quoting-style=c)

if i try to tabcomplete in that directory, i get the following backtrace:
If i'm leaving some vital information out, please say so and i will do
my best to help.
