Game crashes on blacksmith's quest

[maciass]

i come across the zintu village with blacksmiths quest "search for sledgehammer", how i gone with this:

1. stolen the key to the chest from blacksmith
2. interrogated everyone pinpointed in the quest log
3. got back to blacksmith
4. he memories that he left the hammer in the chest but... he has no key
5. i give him the key which i stolen before from him
6. game crashes with error:

"
Call stack functions:
0001:0003626E C:\...PlanetAlcatraz.exe
0001:00010C16 C:\...\PlanetAlcatraz.exe
"

i tried to obey this with just stelaing the hammer and giving it back to blacksmith, but then i have no dialog option to improve my katana. Blacksmith keeps saying that he will improve my katan for 15,000 coins, i have above 300,000 but only dualog option which i have is "Everything clear... i come back when i have money"...

Any hint? I'm running version 1.06 with wine for mac osx. Attaching bug report also.
