Hi Christophe,

Thank you for your prompt answer!
I just downloaded the Automated Nightly Build Linux from the site (
http://www.geuz.org/gmsh/bin/Linux/gmsh-nightly-Linux.tgz)  and I still
reproduce the problem,

attached you can find a screen capture showing the gmsh nightly build
version and the error message in the console when opening the med file,

Thank you,

Luca
