Turns out this was caused by me having set the default project path to a nonexistent path. This should be fixed in upstream MonoDevelop probably?

[aBothe]

Sure. Probably. Do you want to try to fix it and send them a pull request? Or shall I try to do it?

[alexrp]

I'll investigate one of the next couple of days and see what I can do. I have push rights for MonoDevelop, so the fix will probably go in faster if I do it.
