The log is generated with wine older then 1.9.10. It still has bug in mbtowc
call that was fixed by a36b5f0741ac7e6a44aaa9d804ebdb7524186723 commit.

Relevant part of log:
0008:0009:Call msvcr71.mbtowc(0033dc48,01003cec ".",00000003) ret=10caf796
0008:0009:Call KERNEL32.MultiByteToWideChar(000004e4,00000000,01003cec
".",00000003,0033db7e,00000001) ret=7eb601d5
0008:0009:Ret  KERNEL32.MultiByteToWideChar() retval=00000000 ret=7eb601d5
0008:0009:Ret  msvcr71.mbtowc() retval=ffffffff ret=10caf796

(in current code mbtowc will never call MultiByteToWideChar with 4th parameter
== 3).

Please attach log running wine 1.9.10.
