[darcs-devel] [issue1488] fromJust error in WhatsNew (apply_to_slurpy)

Marnix Klooster <marnix.klooster+bugs.darcs.net at gmail.com> added the comment:

By logging all executions of the darcs binary, I found out that zsh completion
(on my Ubuntu 9.04 system implemented in script
/usr/share/zsh/functions/Completion/Unix/_darcs) does a 'whatsnew -sl .' command
in the not-yet-added Foo/Bar directory, which triggers the bug.  So a simple
reproduction scenario is:

  rm -fr darcstest
  mkdir -p darcstest/Foo/Bar
  cd darcstest
  darcs init
  cd Foo/Bar
  darcs whatsnew -sl .

And also with my current darcs version...

  $ darcs --exact-version

  ] 
  
  $

...this results in the reported error message:
