Get error "You must select at least one layer" or something like that.
Switch to background document.
Discover that selected layer (vector icon) is deleted and replaced with grey square of same dimentions.
I am so happy right now that I backup Icons file :)
Update: Happend again just now. No error this time, just no effect in active document. Layer in background document was not deleted, but renamed and placed in group with grey square.
