Details:
As reported a few times now by gorillaz (aka
master) in the forum, sometimes the server
crashes with the following backtrace:
#0 0x00007f1f06fe5fb5 in raise () from /lib/libc.so.6
No symbol table info available.
#1 0x00007f1f06fe7bc3 in abort () from /lib/libc.so.6

Immediately suspicious is the tech=199 argument
to get_invention(), since 199 is A_UNSET.
In trunk get_invention() is renamed to
player_invention_state(), but otherwise the code
appears the same, so it is probably affected too.
