Hello. That's it: I corrected the bug, even though Gimp does not display the progress disc anymore during the transformation (but I don't care).
I only applied partially Massimo's patch: the lines to modify in gimp- gegl-utils.c do not exist, gimpoperationcagetransform files are in app/gegl/ and not in app/operations/, and gimpoperationshapeburst files do not exist anymore. Here are the modifications I made in both gimpoperationcagetransform files. ** Attachment added: "gimpoperationcagetransform.tbz" https://bugs.launchpad.net/ubuntu/+source/gimp/+bug/1614593/+attachment/4727182/+files/gimpoperationcagetransform.tbz -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gimp in Ubuntu. https://bugs.launchpad.net/bugs/1614593 Title: gimp freezes at end of cage-base transform Status in gimp package in Ubuntu: New Bug description: Hello. I am currently unable to apply the cage-base transform, whatever the image: at the end of the two first computations (creation of the cage and first deformation), gimp freezes (at the last pixel of the circle)! And no way to get it back... Except closing.
