--- Comment #147 from YS1 www.salmon.yann@free.fr --- Hello,
I did not check the backtraces but want to give some good news : Civ5 was ported to Linux by Aspyr in June, so using wine is not needed anymore. Just install the Linux version of the Steam client and supply the credential of your account. The Linux version of Civ5 will download.
I did not try to load a game saved under the Windows version that I used to use, because the revision differs.
