If you know how to debug, you could use gdb /usr/bin/harbour-osmscout-server issue "run" in gdb and see what happens. It will probably give lots of messages regarding missing symbols, but maybe we can pull something out of it. When it crashes, see what "backtrace" command would give. Since the server passed Harbour checks, I presume that this bug does not show up on clean installation. You could also try to move away configuration file (please move, don't delete, so we could examine it later!): mv .config/harbour-osmscout-server/harbour-osmscout-server.conf ~/harbour-osmscout-server-send-for-repair.conf then move away Maps.OSM (if the folder was as proposed by default) and try to start server again. If that doesn't help, try to reboot (maybe something is wrong with the tablet state?). Would be good to know if there are other tablet users around and if they see the same error...
