libtext-unaccent-perl segmentation fault

[Jochen Barth]

Hi,
I've got core dumps caused by libtext-unaccent-perl (ubuntu 16.04, all packages upgraded);
the same error is fixed already on debian:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=848156

After compiling the source package from debian here:
https://packages.debian.org/source/stretch/libtext-unaccent-perl
everything works fine.

Kind regards,
J. Barth
