Thanks Laurent, that's great news. So it must be some rather specific usage
that's causing this Mono/Snow Leopard issue to surface.
I don't have any System.Drawing or System.Windows.Forms dependencies with
the current version I'm testing. I've removed those as soon as monobjc has
stopped its own dependencies on those libraries. This also means that X11 is
not involved in any way.
Making some changes to my software also seemed to create the crash without
any explicit threading involved (I think).
Here are the logs (Mac OSX log + the monobjc tracing):

Wanted on Snow Leopard
Hello,
@Franky: Until now, I have tested the 27 samples applications on Core
Duo and Core 2 Duo processors. On both platforms, the application runs
as a 32 bits process, with no problems or crashes.
@Everyone: Does the application that crashes uses System.Drawing or
System.Windows.Forms ?
Regards, Laurent Etiemble.
