The missing guard of ReleaseStgMedium also explains the crash on Fedora
http://test.winehq.org/data/f3b9fb554dd116c881422098738a1f0223087cd1/wine_as...
clipboard.c:1356: Test failed: got 80040064
clipboard.c:1358: Test failed: got 0
=>0 0x684074aa ReleaseStgMedium

Of course, that does not explain why the clipboard metafile retrieval fails
with such curious errors on Fedora Core and MacOS but succeeds on Ubuntu
Intrepid.
