Hi stephane

can you tell us on which OS and version

This is Gentoo Linux. There is no such a thing like a version. There are kernel and a lot of software. Kernel version: # uname -a Linux tp 4.9.6-gentoo #1 SMP Thu Jan 26 17:04:47 EET 2017 x86_64 Intel(R) Core(TM) i7-6700HQ CPU @ 2 I found crash.dmp near pharo-ui,.60GHz GenuineIntel GNU/Linux Let me know please if I could provide more info on this matter.

and which VM do you use (there is a System report browser where you can find the information.

It is downloaded by means of the command: wget -O - get.pharo.org/50+vm | bash AFAIU, the latest VM is downloaded by means of this command. I opened pharo-ui: ./pharo-ui Pharo.image > pharo.log and it was opened for a while, but it crashed when I tried to get information from System report browser. After that, I cannot open pharo-ui anymore. Two log files are attached to this email. Best regards, Andriy
