Hi All, I would confirm this bug I am having the same issue:
Traceback (most recent call last): File "/usr/bin/reportbug", line 2233, in <module> main() File "/usr/bin/reportbug", line 1107, in main return iface.user_interface() File "/usr/bin/reportbug", line 2149, in user_interface package, severity, mode, charset=charset, tags=tags) File "/usr/bin/reportbug", line 182, in handle_editing editor, charset) File "/usr/lib/python3/dist-packages/reportbug/ui/gtk2_ui.py", line 1561, in func op = klass(parent) File "/usr/lib/python3/dist-packages/reportbug/ui/gtk2_ui.py", line 539, in __init__ self.widget = self.create_widget() File "/usr/lib/python3/dist-packages/reportbug/ui/gtk2_ui.py", line 1173, in create_widget expander = Gtk.Expander("Other system information") TypeError: GObject.__init__() takes exactly 0 arguments (1 given) I am using Debian Testing/Sid, kernel 4.8.0-2-amd64, and xfce4 4.12.3. I would confirm also it's related with GTK in general, I switched from a GTK3 theme to a GTK2 and the issue is always the one above. Thanks, Daniel
