Hi folks,��I take a fresh Pharo6.1 (spur64), load a git repository and save the image. When reopening I get a segmentation fault. OS is ubuntu 17.04/64 bits.��I just��cannot��make it work, tried with all the vms I could (vmI61, vmT61, vmLatest70, vmTLatest70). I suspect it is related to using git but I'm not even sure.

Below I put the involved��code, crash dump at the end (seems to be the same with any vm). btw, the vmILatest70 script does not seem to work (curl https://get.pharo.org/64/vmILatest70 | bash).

Any ideas?
