Hack for keeping things from crashing

Context_QueryInterface fails on the UUID
{000001da-0000-0000-c000-000000000046}, resulting in .NET immediately crashing
even though nothing is seriously wrong.  This UUID appears to be related to the
error handling in .NET, with the attached hack the application spawns an error
dialog that can be dismissed.  How I <believe> this is supposed to work is that
Context_QueryInterface should work for any IUnknown compatible interface
(anything defined with DEFINE_OLEGUID).  In order to do this I think the
function should test that the UUID fits the mask
{XXXXXXXX-XXXX-XXXX-c000-000000000046} instead of testing for specific IDs.

Steps to Reproduce:
1) Start with a fresh "~/.wine" if you want to be "safe", I've found that .NET
can have issues with an old install
2) Install vcrun2005 using winetricks
3) Install .NET 2.0 (dotnet20) using winetricks (and 'corefonts' if you don't
have them from your distro)
4) Install Launchpad Enhanced
5) Install or copy StarWars Galaxies into the Program Files folder
5) Run Launchpad Enhanced

Note: This MIGHT be a duplicate of Bug #11504.
