    Description

      In openSUSE Tumbleweed (Qt 5.5.1), kwin_x11 crashes on session start (but then works fine after restart). Stack trace looks like this:

      raise
KCrash::defaultCrashHandler(int)
<signal handler called>
as<QV4::RegExpObject>
toVariant
QV4::ExecutionEngine::toVariant
QQmlPropertyPrivate::writeBinding
QQmlBinding::update
setEnabled
QQmlObjectCreator::finalize
QQmlComponentPrivate::complete
QQmlComponentPrivate::completeCreate
QQmlComponent::create
Aurorae::Decoration::init
KWin::Decoration::DecorationBridge::createDecoration
...

      (full output of "bt full" gdb command attached).

      Reported this to KDE bugzilla (https://bugs.kde.org/show_bug.cgi?id=355274), was closed as a duplicate of another bug which is considered to rather be a Qt issue.
