Comment 2 for bug 153664

I can vouch for this. I have tried to create a GTK# project on several occasions over the past months. Using several versions of monodevelop, both repository pachages and source builds.

Monodevelop works just fine, right until I attempt to use any form of GTK# project.
I have been trying it over and over again, to see if there is a pattern and II am now fairly certain that the crash occurs when I try to Save any changes in a solution/project that contains GTK# code and references.

In simple terms, just hitting ctrl-s will cause the crash in almost all situations for me.
I have included the error output in the attachment.
