Detecting QT-Version of Trinity

Hello Trinity team. First of all, I would like to thank you for your excellent work and secondly I would ask for a hint with qt-creator. Qt-Creator is, may be you know, an execellent IDE not only for developing QT applications. Yesterday I updated my Qt-Creater from version 2.2.0 to 2.3.0. When start the program from a shell, I can see a message which say some thing like "can't determine QT version" and the program ended imedeatedly, if the program is started in a Trinity environment. If the X server is forwarded - using "ssh -Y" - the program starts in a KDE 3.5 (Debian Lenny) environment without problems. At least my question is, does someone know how the QT version can be detected and has something changed in Trinity. May be, that Nokia i.e. the programm does not accept version 3.5.11 because it is not an official release. Thanks for your help and/or ideas Rolf
