[Freeciv-Dev] cvs client assertion failure on game start

[Andy Smith <andy@xxxxxxxxxxxxxx>]

I was playing a game with cvs server and client, did a cvs up just
now and rebuilt both, restarted the server and loaded the save game.

Now when I start the game or connect my client to a started game,
the client has an assertion failure:

civclient: attribute.c:238: unserialize_hash: Assertion `inserted' failed.

Is this an expected hazard when playing with cvs versions (maybe my
save game became incompatible or something?) or should I submit a
bug?  Core file && save game available.
