[Bug 18071] Core Media Player - installer "Cannot read access control list"

--- Comment #8 from Alex   2010-06-01 09:28:50 ---
I've submitted a test to WineTestBot
(https://testbot.winehq.org/JobDetails.pl?Key=2414)

and what I understand is that a security descriptor may be NULL if at least one
pointer is not NULL. Otherwise, it returns ERROR_INVALID_ARGUMENT.

So I guess doing what comment #3 suggests is not sufficient.
We should check that the "at least" condition and then allocate what's needed.

But before sending a patch, I'd have your opinion.
So what do you think ?
