[MonoDevelop] Crashing opening projects

[Jon Cosby]

Need help here. I have an unhandled exception trying to open MonoDevelop
projects in v. 0.15. MD just crashes starting a new project or opening
an existing one. The output for a new GTK# app is

------------------------------------------------------------------------------------------------------------------------------------------------

Crashes in winforms as well. This started as soon as I upgraded from
0.13 to 0.15.
