I was using 1.12.1-dev-test client, but don't know if this can also happen with
unpatched 1.12.1-dev client (I think so, that's why I'm sending the report
here). Yes and server was 1.12.0 (civserver.freeciv.org:5555). This bug occured
about five times during the game. Something like this happened: I destroy
defenses of the city using ironclad. Then capture city with my knight (it was 
on caravel). I couldn't see the whole area of the city which I captured (Maybe
this can help you to the bug down). The result: Client crashes with the
following message:

civclient: cma_core.c:442: can_field_be_used_for_worker: Assertion `known ==
TILE_KNOWN' failed.
