Title: Valgrind warning when theme is changed from MainViewStyle.qml Status in ubuntu-ui-toolkit package in Ubuntu: In Progress Bug description: We are getting this warning in valgrind (with Qt 5.3) ==20334== Invalid read of size 8 ==20334== at 0x581568A: QQmlObjectCreator::finalize(QQmlInstantiationInterrupt&) (qrecursionwatcher_p.h:94) ==20334== by 0x57A5A82: QQmlIncubatorPrivate::incubate(QQmlInstantiationInterrupt&) (qqmlincubator.cpp:357) ==20334== by 0x57A6215: QQmlEnginePrivate::incubate(QQmlIncubator&, QQmlContextData*) (qqmlincubator.cpp:95) ==20334== by 0x57A169C: QQmlComponent::create(QQmlIncubator&, QQmlContext*, QQmlContext*) (qqmlcomponent.cpp:1072) ==20334== by 0x5DCE449: QQuickLoaderPrivate::_q_sourceLoaded() (qquickloader.cpp:721) ==20334== by 0x5DCE5E7: QQuickLoaderPrivate::load() (qquickloader.cpp:604) ==20334== by 0x581564D: QQmlObjectCreator::finalize(QQmlInstantiationInterrupt&) (qqmlobjectcreator.cpp:1202) ==20334== by 0x57A1076: QQmlComponentPrivate::complete(QQmlEnginePrivate*, QQmlComponentPrivate::ConstructionState*) (qqmlcomponent.cpp:932) ==20334== by 0x57A1108: QQmlComponentPrivate::completeCreate() (qqmlcomponent.cpp:968) ==20334== by 0x57A0FCF: QQmlComponent::create(QQmlContext*) (qqmlcomponent.cpp:795) ==20334== by 0x5DD538E: QQuickView::continueExecute() (qquickview.cpp:489) ==20334== by 0x5DD5AB3: QQuickViewPrivate::execute() (qquickview.cpp:133) ==20334== by 0x407045: startShell(int, char const**, void*) (main.cpp:162) ==20334== by 0x407A74: main (main.cpp:227) ==20334== Address 0x20df8968 is 104 bytes inside a block of size 112 free'd ==20334== at 0x4C2C2BC: operator delete(void*) (vg_replace_malloc.c:503) ==20334== by 0x5815FB0: QQmlObjectCreator::~QQmlObjectCreator() (qqmlobjectcreator.cpp:156) ==20334== by 0x57A52AA: QQmlIncubatorPrivate::clear() (qscopedpointer.h:62) ==20334== by 0x57A53C6: QQmlIncubator::clear() (qqmlincubator.cpp:577) ==20334== by 0x5DCD7CF: QQuickLoaderPrivate::clear() (qquickloader.cpp:95) ==20334== by 0x5DCEB02: QQuickLoader::setSourceComponent(QQmlComponent*) (qquickloader.cpp:472) Because MainViewStyle.qml is replacing the theme once it gets loaded (if it needs to go Dark) and we're basically changing the component in MainView.qml while the component is being loaded and it seems Qt doesn't like that. Not sure if it could be argued this is a Qt 5.3 bug, haven't tried if the warning is there in Qt 5.2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-ui-toolkit/+bug/1330510/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
