It is important to note that providers (GDAL,GRASS,SAGA,OTB) are disabled. Enabling them just add more noise to bug report.

All these warning are shown only if it see any duplicate parameters but it shows error that, providers are loaded even if nothing go changed.
All providers are refreshed in ConfigDialog.accept. see below
https://github.com/qgis/QGIS/blob/master/python/plugins/processing/gui/ConfigDialog.py#L333

Is it possible to not load all of them every time?
