Error with Frescobaldi and python-poppler

[Jaime Oliver La Rosa]

Hi all,

I am encountering this problem when trying to engrave any score in Frescobaldi. The score compiles fine, but I can't see the preview, and I get the error below as described in this post:

https://github.com/wbsoft/frescobaldi/issues/838

Is there a known solution for this?

I am using Ubuntu 17.04, Lilypond 2.18.2-7 and Frescobaldi 3.0.0~git20161001.0.eec60717+ds1-2

best,

J
