[QGIS-Developer] Empty style manager in QGIS 2.18

[matteo]

Hi guys,

I have a problem with 2.18 version compiled from source on a Linux
machine. The style manager is completely empty. I cannot see any kind of
symbol (marker, line, etc) even from the layer properties.

It happens also with the --configpath options.

QGIS 3 works perfectly.

Someone is facing the same problem?

Thanks for any suggestions

Cheers

Matteo
