First step is to take XWin out of the picture.  If this is a generic
problem with getmntent, then a standard getmntent loop should show the
same behaviour:

  #include <stdio.h>
  #include <mntent.h>

  int main ()
  {
    FILE *fp;
    struct mntent *mnt;

    fp = setmntent ("/etc/mtab", "r");
    while ((mnt = getmntent (fp)) != NULL)
      printf ("name: <%s> mount point: <%s> type: %s flags: <%s>\n",
	      mnt->mnt_fsname, mnt->mnt_dir, mnt->mnt_type, mnt->mnt_opts);
    endmntent (fp);
    return 0;
  }

Now the question is, if the same problem occurs, why?  Please paste
the contents of /etc/fstab and, if it exists, /etc/fstab.d/$USER
into your reply.
