Title:
  SDL 1.2 crashes on snappy, breaks scummvm

Status in libsdl1.2 package in Ubuntu:
  New
Status in libsdl1.2 source package in Xenial:
  New

Bug description:
  I was trying to use snapcraft to snap flight-of-the-amazon-queen. To
  my dismay I found that scummvm crashes on initialization. Some
  debugging in gdb lead me to a bug libsdl1.2 in get_progname(). The
  error case, which doens't occur outside snappy confinement cause the
  function to return null, leading to a crash when the data is
  subsequently used without checks.

  I've patched the function to return "unknown" (as it does in other
  cases) and tested that this works correctly. The debian/patches file
  patch is attached. I would like to SRU this fix into xenial given the
  high impact of snappy and the negative effect this bug has for each
  application using SDL.

  [Test Case]
  TBD (snapcraft.yaml with flight-of-the-amazon-queen)

  [Regression Potential]
  None, this fixes a crash that occurs only on snappy. The code in question is clearly broken, returning NULL from a function that never returns NULL otherwise.
