The bug title says "Wine should warn when ulimit -n needs raising", so the fix for this specific bug is to warn the user.
As you can see in the original report Wine *already* reports correct error message to the user.
I believe that any other application that uses a lot of file handles would just silently break without an apparent reason. Wine does a better job.
This bug should be marked as invalid.
