MTS crash when profiler true, (string expected, got table)

[Festus1965]

Minetestserver 0.4.16 - on Ubuntu 0.4.18

minetest.conf mit
profiler.load = true

(beyond it did not start even some time)

as soon I have an digtron in the hand coming this
and others also = (string expected, got table)

Code: Select all

so solve to use profiler, start without profiler, take the digtron into a chest, shutdown, activate profiler restart is ok ...
bad way to get some new profiler saves of my server

edit: even digtron is false - just running out might have loaded some other table, and crashed ...
so I need to run a closed, non public copy to get it run for some hours, getting "some" data
