[SOVLED] qtcreator crashes in design mode

Hi,
For some time now Qtcreator (from testing - 3.6.1) crashes when entering desing mode ( same goes for designer-qt5 ) with log:

QMetaProperty::read: Unable to handle unregistered datatype 'SelectionBehavior' for property 'QTabBar::selectionBehaviorOnRemove'
Error while reparenting!
Designer: A class name mismatch occurred when creating a widget using the custom widget factory registered for widgets of class KDialog. It returned a widget of class QDialog.
No frame loaded
No frame loaded
No frame loaded
QMetaProperty::read: Unable to handle unregistered datatype 'ActionTypes' for property 'KShortcutsEditor::actionTypes'
Cannot mix incompatible Qt library (version 0x50501) with this library (version 0x50600)
KCrash: Application 'qtcreator-bin' crashing...

kde (15.20) and qt(5.6) from testing.

Any ideas how to fix this?

Re: [SOVLED] qtcreator crashes in design mode

For me it is

/usr/lib/qt/plugins/designer/libqdeclarativeview.so

..from qt5-quick1 5.5.1-10 that made trouble after the update to 5.6 hit me. If its another plugin for you then you can test them one by one by moving the .so files somewhere else until designer doesnt crash anymore (and move them back when you found the offender). Probably there is another finer, better way but I cannot see which exact version of Qt a plugin file wants.

I've also noticed this bug. The mentioned plugin is indeed the cause of the problem. It is part of the qt5-quick1 package which has been removed from Qt with the 5.6.0 update and hence hasn't been updated like the other modules. Since nothing depends on it, you can simply remove the qt5-quick1 package to resolve this issue.

I had the same problem but the cause was phonon-qt5-vlc package. Removing it fixed the crash.
