I have got the same problem on Maverick with latest Kernel release $ uname -a Linux cube64 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:44 UTC 2011 x86_64 GNU/Linux
sysinfo fails with a Null reference $ sysinfo Exception in Gtk# callback delegate Note: Applications can use GLib.ExceptionManager.UnhandledException to handle the exception.

I cannot explain why.
