[Bug 41398] Starcraft 2 Editor: Crashes when Battle.net login dialog is presented

--- Comment #16 from Andrew Smart <svor1988(a)gmail.com> ---
Thank you very much Bruno and Erich! You made the path very clear to me.

I just downloaded wine-2.0-rc2 (the zip) and built it. I renamed the native
shlwapi and forwarded UrlCombineW to it.

Looks like the native UrlCombineW does the same thing. As proof I did this
right I put a question mark "return-?" in the trace:
0051:trace:shell:UrlCombineW (base
L"http://nydus.battle.net/S2/enUS/client/regions?build=enUS&targetRegion=0&hom...",
Relative L"http:///service/s2/regionsxml/regions.xml", Combine size 0, flags
24000000)
0051:trace:shell:UrlCombineW return-? len=42, (null)
0051:trace:shell:UrlCombineW (base
L"http://nydus.battle.net/S2/enUS/client/regions?build=enUS&targetRegion=0&hom...",
Relative L"http:///service/s2/regionsxml/regions.xml", Combine size 42, flags
24000000)
0051:trace:shell:UrlCombineW return-? len=41,
L"http:///service/s2/regionsxml/regions.xml"

So, I guess the issue is elsewhere.

Further proof:
HRESULT WINAPI UrlCombineW(LPCWSTR pszBase, LPCWSTR pszRelative,
         LPWSTR pszCombined, LPDWORD pcchCombined,
         DWORD dwFlags)
{
    //...

    TRACE("(base %s, Relative %s, Combine size %d, flags %08x)\n",
debugstr_w(pszBase),debugstr_w(pszRelative),
pcchCombined?*pcchCombined:0,dwFlags);
    ret = SHLWAPI_NATIVE_UrlCombineW(pszBase, pszRelative, pszCombined,
pcchCombined, dwFlags);
    TRACE("return-? len=%d, %s\n", *pcchCombined, debugstr_w(pszCombined));
    return ret;

When using the native DLL, at first I got:
000b:trace:seh:raise_exception code=80000100 flags=1 addr=0x7bc5eb4c
ip=7bc5eb4c tid=000b
wine: Call from 0x7bc5eb4c to unimplemented function
ntdll.dll.EtwUnregisterTraceGuids, aborting

So I had to define ntdll.EtwUnregisterTraceGuids, which is the same thing as
ADVAPI32.UnregisterTraceGuids (and the ADVAPI32 one forwards to the ntdll one).

I'll tinker some more and see what I can find out.
