Bug MonoDevelop: "Error while getting object for node in path 'MonoDevelop/Core/PlatformService'"

Hey Unity Forums!

I'm super grateful that there's starting to be some Linux support for Unity3D.

I just installed the experimental build on Linux Mint. So far the interface has some bugs, but nothing I couldn't work around.

However, upon opening C# scripts in MonoDevelop, I get this message:



I can continue using MonoDevelop, however there's no auto-complete whatsoever, and it instead opens up to "open new project" window.

Anyone have a way around this, or perhaps a fix?

System Details:
OS: Mint 17.2 rafaela
CPU: AMD FX-8320 Eight-Core @ 3.5GHz
GPU: Gallium 0.4 on AMD JUNIPER

Thank you!

To those having this error, even in Ubuntu, the resolve is just to install the gtk-sharp plugin like so:

sudo apt-get install mono-complete mono-addins-utils gtk-sharp2 gnome-sharp2
