Comment 7 for bug 1251178

> Maybe this package could be added as a dependency in newer releases?

We would like to make Qt 5 default, but unfortunately this will break lots of legacy Qt 4 code. So we cannot do that soon, maybe in future...

> There is also perhaps an upstream bug where qtchooser could try the "other" qt version if one fails. (I had installed qdbus5, and qtchooser was trying qdbus4, which was not installed or wanted.)

The fallback mechanism exists (in qtchooser 52-gae5eeef and newer versions), but only for some tools: <https://code.qt.io/cgit/qtsdk/qtchooser.git/tree/src/qtchooser/main.cpp#n528>. qdbus is one of them, so if you have qdbus-qt5 installed, qtchooser will use it even if you have no qt5-default package installed. If that is not the case, please let us know your qtchooser version and the console output.
