Description

since re-compile, 'LC_MESSAGES=en_US.UTF-8 svn ls
http://foo.bar.baz/svn/qux/trunk' crashes with SIGSEGV.
unusual condition, successfully finish if remove 'LC_MESSAGES=en_US.UTF-8'.

anyway, trace with gdb, 

>Breakpoint 4, find_entry (ht=0x80694b0, key=0xb77f9897, klen=15, val=0x80655d0)
>    at tables/apr_hash.c:274
>274         he->next = NULL;
>(gdb) p (const char *)key
>$16 = 0xb77f9897 "svn:auth:config"

....

and, do ugly hack to apr_pstrdup for key (attached), works without SIGSEGV.
