msi:RECORD_StreamFromFile bug, help needed

[robert.van.herk at serioustoys.com]

I am not able to reproduce the bug anymore :-S.

I hope it'll pop up in the coming days again, if so, I will send you the trace :-).

I'll also give the sharing thing / SHCreateFileStream a try and see if I can come up with a unit test...

Regards,
Robert

Can you please open a bug report for this and attach a +msi,+msidb trace?
