[ubuntu-mono] [Bug 663381] Re: System Tools -> Sysinfo -> System option fails

[grikdog]

This info is provided by terminal start.  The etiology is the same;
i.e., selecting the first item ("sysinfo") in the menu ALWAYS causes
this same crash.

Status in “sysinfo” package in Ubuntu: New

Bug description:
Binary package hint: sysinfo

If you select the System option in Sysinfo, the application quits.  This happens every time on my Maverick on Dell Inspiron 1525.
The other options below System work as expected.

This did NOT happen in 8.04 to 10.04.  I suspect it is either an old regression, or peculiar to Gnome or desktop.
