Official Debian packages will always be the slowest moving simply due to the fact of having to deal with buildds and having to ensure that the packages build on all 11 arches. Until last week KDE couldn't have been rebuilt reasonably regardless of if I had time to do it or not, qt simply wasn't ready. As far as I know all the maintainers were aware of this issue and it was even mentioned on this list, Ralf sent a message mentioning what would have to be changed to packages building against Qt. I will most likely have updated debs in sid by the end of this weekend (barring anymore computer trouble).
I really wish dirk would fix the s390 bug in acinclude.m4.in already, he is aware that the bug exists but hasn't committed the 2 line fix for it. :\ Chris
