Esteban is trying to understand why he cannot register to this mailing-list and he asked me to past the following so I do it.
"first, as Stef says we cannot do magic and SpecGtk relies on Gtk3. More specific, it relies in a specific version of Gtk3, in this case you need Gtk 3.24 or newer. if you have an older linux version, is likely you also have an older Gtk3 version... hence the crash. this is not a bug but I agree we need to add a version validation to not crash but instead show a message” Stef
