Plugin path preferences not working


I just upgraded to Natron 2.2.5 from a June 2016 version something.
Now the plugins I have placed in directories that are pointed to in the “Edit > Preferences > Plug-ins > OpenFX plug-ins search path” are no longer loaded. If I use the OFX_PLUGIN_PATH environment variable they are loaded, so I think there is something broken with the path settings inside Natron.
