Hi, thanks for the fast response and apologies for disappearing for a couple of days!
Versions are as follows:
Gimp - 2.10.6
G’Mic - 2.3.4
Both using ubuntu 18.04 and this ppa
I ran gimp from the command line to try and source some kind of detailed output but sadly the segfault just looks like this:
*WARNING* missing babl fast path(s): "Y u16" to "Y' u8"
/usr/lib/gimp/2.0/plug-ins/gmic-gimp-qt/gmic-gimp-qt: fatal error: Segmentation fault
/usr/lib/gimp/2.0/plug-ins/gmic-gimp-qt/gmic-gimp-qt: fatal error: Segmentation fault
/usr/lib/gimp/2.0/plug-ins/gmic-gimp-qt/gmic-gimp-qt: fatal error: Segmentation fault
free(): corrupted unsorted chunks
(It crashes when creating the preview)
EDIT: Misinterpreted your testing instructions originally. So:
no preview = All is well initially, crash on hitting apply or ok
threshold = The entire preview box is white, no crash
erosion/dilation = same as threshold
final image = crash
