After the upgrade from Leap 42.3 to Leap 15.0, the GIMP does not work anymore.
Started from the menu (or the Alt+F2 commandline) almost nothing happens. A
symbol appears in the taskbar for some seconds and that�s it. Trying the same
from the command line shows the following (sorry for it is in German!):
GEGL-Message: Fehler beim Laden von Modul �/usr/lib64/gegl-0.3/exr-load.so�:
/usr/lib64/libIlmImf-2_2.so.23: undefined symbol:
_ZN7Iex_2_27BaseExc6assignERNSt7__cxx1118basic_stringstreamIcSt11char_traitsIcESaIcEEE
Speicherzugriffsfehler (Speicherabzug geschrieben)

Must give in I�m not an expert, but can supply any helpful information. 
Thanks for your help!
