Hello again Alexandre,
This is indeed an odd issue - do you still get the same minification error with the latest SP version? Also can you please check with your browser's developer tools what prevents the grid pager UI elements from being served properly? This information can help us find the source of the issue.
If this does not help, the best means to proceed is to isolate a simplified working sample of your project and send it attached to a private support ticket. Thus we'll be able to investigate further and provide an appropriate explanation/fix.
