Sure. I'm using the latest mono I built from the SVN source on 08/07/2007. The call stack with file/line info is really wide, so I've attached it as a text file to this message.
Thanks!

Could you execute with "mono --debug app.exe" so that you get line numbers as well? And knowing which version of Winforms you're using would also help
:)
