"poppler-data" package is missing on devices' image

[Stefano Verzegnassi]

On the ubuntu-phone mailing list[1] has been reported an issue about the libpoppler rendering.

Any attempt to load the following document:
http://www.math.sci.osaka-u.ac.jp/~msj-si-2015/msj_si_2015_schedule.pdf

Results in a badly rendered document on the phone (at the first time it was reported for a Bq E4.5, but it's reproducible on any device - personally verified with a Nexus 5).

Testing the same document on a PC, using Document Viewer and other PDF viewer based on the Poppler library, everything is ok.

After a check of the installed packages, both on device and on desktop, and after a search on Google for the error returned in the application log[2], it seemed that the issue was due to a suggested dependency missing on Ubuntu devices ("poppler-data").

By removing that package on my desktop, I am able to reproduce this issue with any viewer.

What I'd suggest is to add the "poppler-data" package in the device system image.

I mark this bug as "critical" for Document Viewer, since we may want to support all the possible PDF documents and the package is default on dekstop image.
This issue affects also all the third party application that use libpoppler to render PDF documents (e.g. Beru, which includes a PDF viewer), and may be even more relevant.
