While at first sight I agree with you, this has to be decided by upstream. We do not patch things without upstream's ACK *except* on very specific cases (security bugs, obvious fixes, etc.). This change could lead to some other undesired behaviour, so please ask upstream to fix it (normally submitting patches to upstream is a good way to help). > It would be best if the JIT could also be disabled at runtime for > libqt4-script, for applications that don't strictly require it, like > plasma, etc. This is the case for another bug, severity wishlist for *upstream* (in this case, Qt). Please do not heasitate in filling it in https://bugreports.qt-project.org/ Kinds regards, Lisandro. -- Lisandro Damián Nicanor Pérez Meyer http://perezmeyer.com.ar/ http://perezmeyer.blogspot.com/
