I just noticed this by accident.
If the window for the decider combinator is open and you try to delete (right click) the combinator it will create a crash.
There is no crash in your log, but I will just assume that it's related to the whole "close gui and it crashed" reports (since you "closed" the gui by deleting the combinator) and move it to duplicates. That bug is fixed in 0.17.11.
