[ubuntu-mono] [Bug 695046] Re: sysinfo crashes on system menu item in right panel

[G4JC]

Confirming. I told some one about the program being useful in #ubuntu
and he told me the System button wasn't working. Sure enough, tested it
myself and it's broken. Got a little more info attached via running
normally in terminal followed by a gdb run attached to the PID.
Furthermore I'm running AMD64 so it's not an i386 only bug.
