           Summary: Battle.net does not launch with error This application
                    failed to start because it could not find or load the
                    Qt platform plugin "windows" in "".

When starting Battle.net the launch fails with error:

This application failed to start because it could not find or load the Qt
platform plugin "windows" in "".

A fix is to go into the subdirectory with the latest version number of
Battle.net (Battle.net.13960 in my case), go to the platform directory and run

$ setfattr -x user.DOSATTRIB qwindows.dll

The bug exists for me since beginning of January.
