I have just found this old thread while experiencing the same problems again. The problem seems to be that Qt somehow reads the locale and starts misbehaving when parsing numbers (it expects comma instead of the dot for decimal separator). If I change the locale, everything starts working. I'm not sure whether this is something that Geant4 or Gate should fix though.
