Today after upgrading ran into gimp not loading due to a gegl error.
GEGL operation missing!
GIMP requires the GEGL operation "gegl:introspect".
This operation cannot be found. Check your GEGL install and ensure
it has been compiled with any dependencies required for GIMP.
this is solved by installing graviz package
sudo apt install graphviz
this is on antiX using the sid repos. Also double check that the
gegl package is installed.
