I was able to reproduce the issue on Ubuntu 16.04 using Pharo7.0-32bit-d13eed2.image. I haven't tracked the cause down, but the problem doesn't exist with the proposed fix I have for symbolic links (fogbugz 18279 https://pharo.fogbugz.com/f/cases/18279/isSymlink-seems-to-be-broken-on-Linux). This patch also updates the code responsible for iterating over directories, which is why it can resolve this issue as well. Cheers, Alistair > On Sat, Oct 7, 2017 at 5:44 PM, Steven R.
