The patch was recently removed from svn, so I suggest updating your
qt-copy installation as follows:
1. svn up qt-copy
2. svn revert -R qt-copy (to remove any previously applied patches)
3. cd qt-copy
./apply-patches (to apply Qt 4 patches by various KDE developers)
Rebuild and install qt-copy
Regards,
Robert.
