Dear Francesco, I'm a member of the new upstream maintainer team.
The bug is quit old. Please try to reproduce that problem with the current upstream version. If you can reproduce it please open an Issue at upstream and link it here.
You still gave us the steps to reproduce.Can you please give some more information about snapshot profile you setup?
I suggest to close that Debian bug report because it seems not distro specific.
Kind Christian Buhtz
