/lib/libc.so.7: slrn dies in LC_ALL=C env on a particular message

Today I came upon a post in rec.arts.anime.misc ...

  8B8AD26D-FF8A-4CCE-A10A-239657B79B2E%[email protected]


... with headers ...

  Content-Type: text/plain; charset=windows-1250
  Content-Transfer-Encoding: binary


... which caused slrn to die with segfault. It was when "LC_ALL" was
set to "C" (no other LC_* variable was set).


slrn also dies while trying to display a reply to that post...

... which has ...

  Content-Type: text/plain; charset=UTF-8
  Content-Transfer-Encoding: 8bit


Previously, slrn would just show the odd charcaters without fuss,
which would be the desired behaviour. Problem remained even after
rebuilding slrn & slang.

The two messages can be accessed from ...

  http://bitter-almonds.com/tmp/slrn-segfault-LC_ALL=C


slrn displayed the messages without problem with ...

  # env | fgrep LC_
  LC_TIME=en_US.UTF-8
  LC_NUMERIC=en_US.UTF-8
  LC_MONETARY=en_US.UTF-8
  LC_MESSAGES=en_US.UTF-8
  LC_CTYPE=en_US.UTF-8
  LC_COLLATE=en_US.UTF-8


Should I file a PR (for libc*)?
