I started up a 'failsafe' session, which is no more than a terminal
and this is what I got:

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.

I am not sure what to do now, as I get the same error every time. It
is at this point that I would fire up my Windows PC and try out the
exe, and then use 'csc' to compile the code and see what I get. So,
to check that the executable was not bad I went off and copied it to
my ubuntu computer (of which I installed what is probably an archaic
version of mono and libgdiplus) and then ran it, and for a split
second it worked (well I saw the GUI in all its 'motif' look-alike),
until I errored on me saying that I did not have a POSIX Helper DLL,
but the main point is that it is compiled correctly. As far as I can
tell the problem is with System.Windows.Forms, and if I knew the
address of your IRC channel, I would, at this point be asking a
developer to take a detailed look at my stack trace. I do run
applications like Mono-develop and a few console applications of my
own creation all the time, so the core mono runtime stuff seems to
befine.

Hi,
As I see in your paste you're running KDE. I've got Gnome and your
sample works right! The only problem can reside in the Desktop
dependent
code. Then you can try it in "failsafe" or "gnome", if you have this
last installed, and report the results.
Regards,
Pedro
