Remove UplayCrashReporter.exe from the .wine/drive_c/Program Files (x86)/Ubisoft/Ubisoft Game Launcher/ directory to fix this bug. The game works fine without it. Backup your /home/xfce/Documents/Assassin's Creed IV Black Flag/Assassin4.ini file, some display setting can cause a black screen.
Unfortunately this didn't help. The game still won't start. I attached a new log file (removedUplayCrashReporter.log)
Use a clean .wine prefix and win7. From winecfg Graphics settings, disable Allow decorate the windows.

Alright, the game launches and runs fine, but crashes during one mission. I'll provide the log when I'll be able to
