[kde] [Bug 320623] Adds Qt binary path to $PATH breaking qtchooser

--- Comment #3 from Ralf Jung <post at ralfj.de> ---
Unfortunately, this is more complicated than I thought: I was about to suggest
to just remove the lines from startkde which add the Qt path to the PATH.
However, if I do that, logging in to a KDE session fails, complaining about
missing/failing qdbus. qdbus fails saying

qdbus: could not find a Qt installation of ''

Probably, that is because of
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=710773 . After adding a
symlink from $HOME/.config/qtchooser/default.conf to
/usr/share/qtchooser/qt4-x86_64-linux-gnu.conf, my KDE session works again.

Now of course I could change startkde to use the qdbus inside the path given by
Qt, but it may very well me that other parts of KDE rely on qdbus being in the
PATH. In this case, what would happen if qtchooser uses another qdbus than the
one of the Qt version KDE was compiled with? Do they all have the same
interface? As the issue I had shows, this makes qtchooser a *very* critical
tool, a misconfiguration here will break all KDE sessions.
