Directory added with trailing slash shows properties set to null

[GoogleCodeExporter]

What steps will reproduce the problem?
1. xar -cf bar.xar file directory/ (the trailing slash is important!)
2. try to list the archive contents using pyxar:

    from xarfile import XarArchive
    XarArchive('bar.xar').getitems()

3. you get segfault and the reason is that the uid is set to null as the
simple program below will show:

#include <xar/xar.h>
#include <stdio.h>

void usage(char* argv[]){
    fprintf(stderr,"Usage : %s archive_name\n",argv[0]);
}

int main(int argc, char* argv[]){
    if (argc < 2){
        usage(argv);
        exit(1);
    }

    xar_t x;
    xar_iter_t i;
    xar_file_t f;

    x = xar_open(argv[1],READ);
    if ( x==NULL ){
        fprintf(stderr, "error opening xarchive: %s\n", argv[1]);
        exit(1);
    }

    i = xar_iter_new(x);
    if (!i){
        fprintf(stderr,"error creating iterator\n");
        exit(1);
    }

    for (f = xar_file_first(x,i);f;f=xar_file_next(i)){
        const char *name, *_type, *mode, *uid, *user, *gid, *group, *atime,
*mtime, *ctime;
        name = xar_get_path(f);
        xar_prop_get(f, "type", &_type);
        xar_prop_get(f, "mode", &mode);
        xar_prop_get(f, "uid", &uid);
        xar_prop_get(f, "user", &user);
        xar_prop_get(f, "gid", &gid);
        xar_prop_get(f, "group", &group);
        xar_prop_get(f, "atime", &atime);
        xar_prop_get(f, "mtime", &mtime);
        xar_prop_get(f, "ctime", &ctime);
        fprintf(stdout,"name %s, type %s, mode %s, uid %s, user %s, gid %s,
group %s, atime %s, mtime %s, ctime %s\n",
                name,_type,mode,uid,user,gid,group,atime,mtime,ctime);
        }
    xar_close(x);
}

One of the files below was created without using the trailing slash, and
the other one with trailing slash.
