[Mono-devel-list] debugging problems

[Chris Nuernberger]

Anyone tried to debug a gtk-sharp app?  The debugger chokes really quick
when I try to do this.  I have built a glade app using monodevelop, and am
just playing around trying to run it in the debugger (mdb).  Here is the
output:

So basically there are a set of libs the debugger can't figure out, and then
when I just try to run the program, it catches a signal 11 (sigsegv).  

I honestly haven't tried to debug a basic program yet, probably should start
with a pure c# assembly, but I figured I would play with gtk#.
