[webkit-gtk] Win32 program crashes when loading pages that have jpg images

[SCU Rock]

   I have fixed this problem. It was not caused by msvcrt.dll, but by
the inconsistency between libjpeg-<n>.dll and the webkit library. The
crash point is shown on my gdb debugger at setjmp() in msvcrt.dll
though. The same bug is mentioned at
https://bugzilla.redhat.com/show_bug.cgi?id=497492.

   I patched a fix and rebuilt libjpeg dll file. Now with the new jpeg
dll, now my program works fine.

Cheers.
