Plugins in qt.conf is not working but QT_PLUGIN_PATH does

I use more than one Qt version on my dev. pc. Therefore I created qt.conf file in binary folder to point to my/used/qt.
Libraries = /home/my/used/x86/qt/usr/local/qt/lib@
Result: QML application with usage of fonts from .../lib/fonts is working as expected.
I wrote another app using the sqldriver and therefore my qt.conf looks like:
Libraries = /home/my/used/x86/qt/usr/local/qt/lib
Plugins = /home/my/used/x86/qt/usr/local/qt/plugins@
Result: Db Driver QSQLITE is not available.
I set up the env variable:
Result: The SQL application works as expected.
I tried to find an environment variable to set the path to the Qt libs and fonts. But I found no solution.
My goal is to have only one way to configure the application environment. Either qt.conf or system variables.
Any suggestions or hints?

Hi, using qt.conf can in some cases fail, because it's slightly more brittle than exporting QT_PLUGIN_PATH (I've written about it "here":http://www.tripleboot.org/?p=536
Just guessing, but if you are calling something like QStyleFactory::keys() first thing in main.cpp, that can be the explanation.
EDIT: forgot, you can also trace the plugins loading in QtCreator, by exporting QT_DEBUG_PLUGINS=1 (or set it in QtCreator/Projects/Build Environment, that worked for me)
