Title:
  smbd crashed with SIGABRT in strlen() while accessing a share from a
  W7 client

Status in samba package in Ubuntu:
  Confirmed

Bug description:
  I tried to access an SMB share hosted on my Ubuntu desktop from my
  Windows 7 laptop.  This is something I do dozens of times a day and
  have not seen a crash report until now.

  The specifics were that I was running Chrome on my Windows 7 desktop
  and I was selecting a file to upload to a website via a mounted
  network share.  That mounted drive is an SMB network share from my
  Ubuntu desktop that allows read access of a directory in my /home
