Not really.  You'll want to use a +file log and follow the handle as it's passed to subsequent calls.  It might also be necessary to use +tid,+relay to see all uses if Wine isn't logging the handle in all relevant functions.

Certainly, look for failed reads, but I wouldn't expect that unless you think the file is damaged vs. what's installed on Windows.  More likely, the game requires external help interpreting the data that is has read, like a compression or image library.  If that's not present or is incomplete in Wine, then that would explain the problem.  The +tid,+relay log may help to identify what the program does next after it has read the data in.
