So this is in the part of the compiler that goes through server-side code to look for quotations to compile. I think we should catch this and show a warning.

Somehow this issue disappeared after deleting bin and obj and recompiling. I'll leave this issue open because I'd still like to investigate what caused it in the first place some time.
