Hi, running eric4 or eric4-configure with latest PyQt4 snapshot results in the following error message. QVariant::load(QDataStream &s): type unknown to QVariant. Any hint on what is going on is appreciated. Versions: Qt 4.4.3 PyQt4, QScintilla2 and sip all latest snapshots. Regards, Detlev -- Detlev Offenbach detlev at die-offenbachs.de
