I'm currently using Qt: 4.7.2 with KDE: 4.7.00 (4.7.0) and the V2,4
binding i386 interface on a kubuntu system.
Lazarus programses compiled for Qt works means starts, but when a
(native?) KDE directory selection dialog is called from the program it
crashes.
This does not happen with V2.1 QT 4.7 enabled interface.
TApplication.HandleException Access violation
QWidget::repaint: Recursive repaint detected
[FORMS.PP] ExceptionOccurred
Sender=EAccessViolation
QPaintDevice: Cannot destroy paint device that is being painted
Such errors comes from sse2/3 code in qt libs and bindings must be compiled with -mstackrealign.

So this binary from V2.4 are not compiled with -mstackrealign. ? And is it possible to have a QT Binary that works from QT 4.5 until 4.7 ? At the moment it seems that V2.1 works with all Qt's before 2.7 and the 2.1 compiled for Qt 4.7 ONLY works with Qt4.7 and not 4.6 / 4.5
