KDE:Qt is the only correct one, that was made clear with the "osc meta prj KDE:KDE4:Factory:Desktop" output.
To create the packages from KDE:KDE4:Factory:Desktop the source code is compiled using the libraries from KDE:Qt, no KDE:Qt44. And if you build using library A and then run using library B you never can be sure of the results.
Also:
Code:
$ osc meta prj KDE:Qt | grep description
<description>This project provides the Qt 4.x.x version that is currently being considered most stable whilebeing reasonably recent. It is a good target to _aggregate or to build against if your particular project or application needs a newer version of Qt. Users are recommended to add this repository if they want to update their Qt.</description>
$ osc meta prj KDE:Qt44 | grep description
<description>This repository contains Qt 4.4.x</description>
KDE:Qt has an updated but somehow stable Qt. KDE:Qt44... well, isn't specified.
If someone still has problems after adding KDE:Qt then there is *another* problem. A good bug report would make sense.
The good news are that in the future we will not have this problem ->
