Fix for the crash

This patch fixes the crash. The problem arises on any app that calls
MsiViewExecute with null hRec. On trunk with patch the installation finishes,
but is still not too happy about the custom action:

err:msidb:msi_table_load_transform no matching row to transform
x100
...
err:msi:ACTION_CallDllFunction Custom action
(L"C:\windows\temp\msi9845.tmp":L"OfficeDataLockPermissions") caused a page
fault: c0000005
...

I don't have time to write a test case right now and submit this properly
(finals), so if anyone has time that would be great.
