$ grep -i icon-theme.cache /usr/ports/www/opera/pkg-plist 
share/icons/hicolor/icon-theme.cache

$ grep -i icon-theme.cache /var/db/pkg/opera-12.02/+CONTENTS 
@unexec /bin/rm %D/share/icons/hicolor/icon-theme.cache 2>/dev/null || /usr/bin
/true
share/icons/hicolor/icon-theme.cache

$ man pkg_create
...
     @unexec command
             Execute command as part of the deinstallation process.  Expansion
             of special % sequences is the same as for @exec.  This command is
             not executed during the package add, as @exec is, but rather when
             the package is deleted.  This is useful for deleting links and
             other ancillary files that were created as a result of adding the
             package, but not directly known to the package's table of con-
             tents (and hence not automatically removable).

I recently tried to make aware opera port maintainer about it
Maintained by: dinoex at FreeBSD.org
but with no effect.
