Sysinfo window closes as soon as it is opend

[DAP]

Binary package hint: sysinfo

I tried Applications->System Tools->Sysinfo
The window opened then immediately closed.

I ran it from the command line. Same thing happened, but I got some error messages out of it:

$ sysinfo
Exception in Gtk# callback delegate
  Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.
