If I install gimp and gimp-plugins-python and than run gimp from the terminal,
I get this error on startup:

Traceback (most recent call last):
  File "/usr/lib64/gimp/2.0/plug-ins/file-openraster/file-openraster.py", line
17, in <module>
    import xml.etree.ElementTree as ET
ImportError: No module named xml.etree.ElementTree
gimp: LibGimpBase-WARNING: gimp: gimp_wire_read(): error

After installing python-xml python-xml package the error is gone. gimp starts
fine even with the error so it probably can be Recommends and not Requires.
