[Pkg-haskell-maintainers] Bug#700329: pandoc hangs using --bibliography

[Carsten Allefeld]

Package: pandoc
Version: 1.9.4.2-2 and 1.9.4.5-2
Severity: normal

Dear Maintainer,

pandoc hangs when using the --bibliography option, if the package
libghc-citeproc-hs-data
is not installed. In this case, pandoc does not give an error message or
aborts, but just hangs there. Because of this, it takes considerable research to
find out what the problem might be, and how to solve it.

The solution is to install libghc-citeproc-hs-data as well. As far as I can
see, this package has recently been added to the recommendations of pandoc.
I believe this is not enough; a standard part of pandoc's functionality is
missing when this package is not there, and moreover, there is not even an
informative message.

I would therefore propose to make libghc-citeproc-hs-data a dependency of
pandoc, or to modify pandoc to inform the user about this "run-time
dependency".

The problem is known upstream, see
  https://github.com/jgm/pandoc/issues/406
but not considered a bug, presumably because installation of pandoc via
cabal automatically fulfills this dependency.

The package version I have actually installed is 1.9.4.2-2 from testing, but
version 1.9.4.5-2 in experimental also misses this dependency.

Greetings,
Carsten
