Somehow I'd missed the first part of your last email--you were right,
I was running mono --debug
/Applications/MonoDevelop.app/Contents/MacOS/monodevelop rather than
/Applications/MonoDevelop.app/Contents/MacOS/monodevelop --debug. I've
got the output now (which I'll also be adding to the bug report
mentioned in my last email):
