Qt not patched for fixing KDE bug 275469 (ghost taskbar entries)

[Harald Sitter]

Since the patches were approved into Qt and passed the sanity checks
there I presume fabo will soonishy cherry pick them into the package.
No particular rush though, they do not added features, so are not
affected by feature freeze, plus release is still quite a bit away.

Though I added them to our global precise todo, to make sure it gets
tracked accordingly.
