This bug is still here. Just found the same exact thing:
The mod Rail Logistics Dispatcher 2 (2.0.24) caused a non-recoverable error.
Please report this error to the mod author.
Error while running event RailLogisticsDispatcher::on_robot_mined_entity (ID 73)
__RailLogisticsDispatcher__/script/entity.lua:40: attempt to index local 'disp' (a nil value)
stack traceback:
__RailLogisticsDispatcher__/script/entity.lua:40: in function 'dispUpdateStop'

__RailLogisticsDispatcher__/script/entity.lua:672: in function 'entityHandleRemoved'
__RailLogisticsDispatcher__/control.lua:138: in function <__RailLogisticsDispatcher__/control.lua:134>
Noted on Nebbeh's solution of just not robotically deconstructing both at the same time.
