Hello everyone,
I've been watching this mailing list for a few weeks now and
finally had the time to get the trunk of basket up and running on my
machine. After poking around in the
BNPView::showPassiveDroppedDelayed() method I think I have an idea of
why we're getting the seg fault. In the line
[2312] m_passivePopup = new KPassivePopup(Settings::useSystray() ?
(QWidget*)Global::systemTray : this);
Settings::useSystray() evaluates to true and so we pass
(QWidget*)Global::systemTray to the constructor of KPassivePopup which
expects a QWidget* as a constructor argument. But Global::systemTray
is a SystemTray which inherits from KSystemTrayIcon which inherits
from QSystemTrayIcon which inherits from QObject. So as far as I can
see Global::systemTray is not a QWidget* and so the C style cast to
QWidget* will produce garbage, causing the seg fault somewhere inside
KPassivePopup.
Hope someone else can figure out what the intent was here, but in the
meantime chaging line 2312 to
m_passivePopup = new KPassivePopup(this);
doesn't seqfault (the popup just doesn't appear over the tray icon).
