Gimp crashes when loading png or jpg

[Piet van Oostrum]

Hello,

Suddenly my gimp crashes when I try to load a PNG or JPG file. It gives the error message:
Plug-in crashed: "file-png"
(/Applications/MacPorts/GIMP.app/Contents/Resources/lib/gimp/2.0/plug-ins/file-png/file-png)

Plug-in crashed: "file-jpeg"
(/Applications/MacPorts/GIMP.app/Contents/Resources/lib/gimp/2.0/plug-ins/file-jpeg/file-jpeg)

This is gimp @2.10.8_0+animation+quartz and gimp2 @2.10.8_2+python27+quartz on MacOS High Sierra.
I upgraded on 26 december and before that it worked. I also uninstalled and reinstalled both gim and gimp2 from source but that did not help.

Is this a known issue?
