I'm not entirely sure how/why that error happens, but right now I reproduced by doing :Kedit node abc (with a valid node name, of course), opening another buffer for another node, writing a label in the "old" buffer, and doing :w.
:Kapply did work (after reloading the object, seems it got changed while writing this issue ;/ )
