memory problem with utf8

[David Wetzel]

hi folks,

I have a bug that shows up when I use utf8 string encoding. Memory is twice 
freed. On NetBSD, you can 
set

setenv MALLOC_OPTIONS AJ
to get a SIGABRT on that. See 
http://netbsd.gw.com/cgi-bin/man-cgi?malloc++NetBSD-2.0
for more information.

The following shows up when I use 

setenv GNUSTEP_STRING_ENCODING NSUTF8StringEncoding
before starting the program

Program received signal SIGABRT, Aborted.

NSISOLatin1StringEncoding as encoding does *not* crash, but then I do not get 
all fancy utf-8 chars...
We tried to debug that but I have no idea what may cause the problem.
If you are able to help, i can give you ssh access.
