Problem with gantt view

HI again.
Now i´m starting to have some issues with the gantt view in projects
I have created a project directly, not from a template, and then just added some tasks.
If i try to go to the gantt view i just get a page with no content and some errors in the logs

My sistem is
Local system with Ubuntu 16.04
PHP 5.6.30-11
Mysql - Ver 14.14 Distrib 5.7.18, for Linux (x86_64) using EditLine wrapper
