[Wine] Warcraft 3 crashes at bnet

[godmarck]

This is the error message I get right after I login to my bnet account:
------------------------------------------------------------------------------------------
This application has encountered a critical error:



FATAL ERROR!



Program:	C:\Program Files\Warcraft III\war3.exe

Exception:	0xC0000005 (ACCESS_VIOLATION) at 0073:6F7D6891



The instruction at '0x6F7D6891' referenced memory at '0x00000078'.

The memory could not be 'written'.
------------------------------------------------------------------------------------------
Also, I can't play LAN games, it simply says "could not connect to network".
Any ideas?
I think this started to happen after the 1.23a patch for WC
