[Bug 278617] Re: login crashed with SIGSEGV in dump_core()

[Mike Gratton]

This can result from a user action using Nautilus:

- right-click a folder
- select "Sharing options"
- check "Share this folder"
- click "Create Share"
- wait for Samba will be downloaded an installed.

I then ended up uninstalling it because I found a better way to share
the directory, but found after that I could not login or use `sudo'.

Running an strace on `login' when trying to debug this showed that the
samba password file was being accessed shortly before the segfault, so
it seems that the presence/non-presence of this file may have been the
cause of the problem.

Note that this might be quite serious as any user that decides to share
a folder might be affected, and they will likely not know how to fix it
as it breaks sudo.
