[Bug 17591] Segfault in wintrust.dll

http://bugs.winehq.org/show_bug.cgi?id=17591

Thanks.  Here's the source of the problem:

trace:wintrust:dump_file_info cbStruct: 12
trace:wintrust:dump_file_info pcwszFilePath: L"C:\Programme\Buhl\Mein
B\00fcro 2009\On4UD.dll"
trace:wintrust:dump_file_info hFile: 0xffffffff
trace:wintrust:dump_file_info pgKnownSubject: <guid-0x002c>

pgKnownSubject is clearly a bogus pointer.  Accessing it is what shows up in
the crash log:
wine: Unhandled page fault on read access to 0x0000002c at address

I'll attach a patch shortly.
