Running 'plasmashell' in Valgrind reports this Qt related warning on each startup (full message below):
==3267== Conditional jump or move depends on uninitialised value(s) ==3267== at 0xB1F14AF: QMetaObjectPrivate::connect(QObject const*, int, QMetaObject const*, QObject const*, int, QMetaObject const*, int, int*) (qobject.cpp:3233) ==3267== by 0xB1F1C87: QObject::connect(QObject const*, char const*, QObject const*, char const*, Qt::ConnectionType) (qobject.cpp:2712)
I don't have an isolated test-case to produce this, but I'm able to consistently reproduce it using the current KDE Frameworks 5-based 'plasmashell' from git master.
I can't tell whether that's a false-positive, haven't found any existing reports regarding this and couldn't get feedback on IRC so far on the impact of this, so feel free to close this report if it's not critical.
