Not a bug in qtdeclarative, you can easily invoke qmlscene using
"QT_SELECT=5 qmlscene", or by specifying a full path to executable
(/usr/lib/MULTIARCH/qt5/bin/qmlscene).

For qtchooser part of the bug, see the bug 1295835.

Title:
  qmlscene doesn't work on 14.04 and 14.04.1 without installing
  qt5-default

Status in “qtdeclarative-opensource-src” package in Ubuntu:
  Invalid

Bug description:
  On 14.04, 14.04.1 and utopic (as of 2014-07-29), qmlscene doesn't work
  :(

  Steps to reproduce:

  1- Boot a live CD image for 14.04, 14.04.1 or 14.10 in "try without installing" mode.
  2- Open a terminal
  3- apt-get install qmlscene
  3- qmlscene

  Expected result:
  - Qmlscene launches and shows a file chooser to open a qml file

  Actual result: Error message:

  qmlscene: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qmlscene':
  No such file or directory

  Now, qmlscene gets installed in /usr/lib/x86_64-linux-
  gnu/qt5/bin/qmlscene. The binary in the path is /usr/bin/qmlscene
  which is symlinked to qtchooser. Interestingly, this symlink exists
  even if qmlscene is not actually installed, which is doubly confusing.

  Qtchooser apparently looks at config files in /usr/lib/x86_64-linux-
  gnu/qtchooser/, and in here I can see:

  lrwxrwxrwx 1 root root 50 Mar 12 10:09 4.conf -> ../../../share/qtchooser/qt4-x86_64-linux-gnu.conf
  lrwxrwxrwx 1 root root 50 May 12 05:44 5.conf -> ../../../share/qtchooser/qt5-x86_64-linux-gnu.conf
  lrwxrwxrwx 1 root root 50 Mar 12 10:09 qt4.conf -> ../../../share/qtchooser/qt4-x86_64-linux-gnu.conf
  lrwxrwxrwx 1 root root 50 May 12 05:44 qt5.conf -> ../../../share/qtchooser/qt5-x86_64-linux-gnu.conf

  but apparently there's no "default.conf" so qtchooser falls back to
  qt4, even though qt5 is installed.

  If I install the qt5-default package, then a default.conf file is
  created in this directory pointing to /usr/share/qtchooser/qt5-x86_64
  -linux-gnu.conf, which correctly instructs qtchooser to use qt5
  binaries. The problem with qt5-default is that it's described as a
  metapackage for development defaults, and indeed, it depends on about
  60 MB of -dev packages which shouldn't be needed if all I want is to
  run qmlscene with a qml file.

  A way to make qmlscene work (maybe by adding the proper dependencies
  to the qmlscene package), or with the installation of a single,
  smallish package instead of a set of unrelated stuff, would be useful.
