Bug description:
qtchooser reads the path to resolve a binary from default.conf which
always points to the architecture qtchooser was built for. e.g.
/x86_64-linuxwhateverblahblah/ on amd64
this in particular means that if one is on amd64 and installs
qdbus:i386 it will replace (i.e. remove) qdbus:amd64 and from that
point on /usr/bin/qdbus (which is backed by qtchooser) will no longer
work because it will look in the x86_64 path but not the x86_32 one.
> qdbus: could not exec '/usr/lib/x86_64-linux-gnu/qt4/bin/qdbus': No
such file or directory
this has a rather grave impact on users that get their qdbus replaced
with qdbus:i386 as large parts of kde software expect qdbus to simply
work (such as startkde - bug 827815) and even platform stuff does
(such as the power button handler - bug 1124149).
and judging from those bugs this can happen rather easily, and has
already happened to a lot of users.
to resolve this qtchooser either needs to also look in the 32bit path
OR the package deps need to be adjusted such that one cannot have a
mixture of arch packages (which I doubt will be feasible because
switching the tooling to i386 will likely cause all of kde/qt to be
switched to i386 too...).
