Client crash on save/load game

Sometimes game (v 0.93) crashes during save or load.
Often there is only client chash - server works.
There was no such behaviour in v 0.92

system: Linux Debian wheezy amd64

UPD: save and log attached
SaveLog.zip (569 KB)

Sorry for delay.
Can you upload logs & savegame (two files) that fails to load? Both can be found in ~/.vcmi directory
