This is the exact same file as on a Windows XP Pro installation. FWIW, the Windows font viewer shows the name as "Arial Black" while KFontview has "Arial, Black". I don't know enough about the inner workings of OpenType to tell the significance of that.
You have 2 ariblk.ttf files installed in your system: /usr/share/fonts/webcore/ariblk.ttf.xxx (which is OK) and /home/steve/.wine/dosdevices/c:/windows/Fonts/ariblk.ttf (which is broken).
Please remove the latter one.
