Thank you.

OK. So I believe the next question is: would you suggest using Geant4
9.5 or 9.6 with the development version? Where can I expect less
problems?

Bingo!

I knew that both Qt and C# love to be user-friendly and happily
consider comma to be the decimal separator, but I didn't think of that
when I stumbled into the problem.

Thank you very much. Using

    export LANG="en_GB.UTF-8"
    export LC_ALL="en_GB.UTF-8"

as well as exporting all the variables for Data files and fixing some
permission problems in G4EMLOW got rid of core dumps in both Qt and
non-Qt version of Gate. (The crash could have been more informative by
telling me that G4LEDATA variable was missing ;)

Now the next challenge would be figuring out where/how to fix the
behaviour in Geant4 or Gate, so that parsing won't depend on locale.

Thank you,
