retext crashes when in preview mode the links points to a non existing file

[nnss]

I created the link in a file in Markdown syntax as

* [Servers](servers)

The preview shows that ok, but when I click on the link, the program crashes and the output is:

matias@aserulo:~$ retext

    raise EOFError('Received 0 bytes from socket while more bytes were expected. Did the sender process exit unexpectedly?')
EOFError: Received 0 bytes from socket while more bytes were expected. Did the sender process exit unexpectedly?
Abortado

This only happens when the LANG/LANGUAGE environment variables are set to es_AR.UTF-8, as a workaround I can open the program without those variables, and works fine (ask to create the file without crashing)

Fixed, thanks for your bug report!

I will also try to do a new Debian package upload soon (but it will take 20 days to migrate to testing, per the freeze policy).
