Comment 58 for bug 292791

Steve: the fix in bug 260687 is making sure /var/lib/samba is created by moving directory creation to the appropriate package. It's not solving the segfault that happens if it's not there.

However here the problem is different, as it happens with an existing /var/lib/samba directory. Emptying the directory usually solves it, by forcing the re-creation of the files in it.
