Short description of error
The environment variable BLENDER_SYSTEM_DATAFILES can be set to allow placing datafiles in different locations. The toolbar icons fail to follow this path and can only be found using the 2.80/datafiles path construct.
Exact steps for others to reproduce the error
Move the 2.80/datafiles folder to a different location than blender and set BLENDER_SYSTEM_DATAFILES to match. Only the toolbar icons fail to be found.
Also setting BLENDER_USER_DATAFILES does not help. Could/should this also be included in the icon search path?
